The ground-breaking ceremony of Shanwei Industrial Park of C-Dada was held

On the afternoon of September 25, 2021, the ground-breaking ceremony of Shanwei Industrial Park of Shenzhen C-Data Technology Co., Ltd. was grandly held in Shanwei high-tech zone. The industrial park is invested and constructed by Shenzhen C-Data Technology Co., Ltd. (hereinafter referred to as “C-Data”), with an investment scale of more than 350 million yuan, covering an area of 30,000 square meters, the building area will be 75,000 square meters after completion.

Lion dance

The ground-breaking ceremony began. First of all, leaders came to the stage to draw eyes for the four auspicious lions.

Painting eyes

Painting eyes for lions means awakening lions and giving them the ability to spread happiness and auspiciousness.

Lion dance

After drawing the eyes, the lion slowly woke up. The awakened lion heard the music and began to dance. At the climax, the lion blesses C-Data with wealth, blessing and auspiciousness through “Caiqing”. “Caiqing”:In Chinese cǎi (pluck) sounds similar to cài ( vegetable) and cái (fortune). In a symbolic way the lion is appeased by the offering and later spreads good fortune and prosperity to all the people.

Immediately, the foundation of C-Data Industrial Park was officially laid,the atmosphere was particularly festive. Mr. Zheng Liangbin, Mr. Lin Jianyou and the senior executives of C-Data jointly lay the foundation. Since then, C-Data Industrial Park has officially started.

Three years ago, due to the expansion of production scale, C-Data sought plots in cities around Shenzhen to build an industrial park, and finally chose Shanwei. Today, the ground-breaking ceremony is officially held.

 Shanwei Industrial Park of C-Dada

The ground-breaking ceremony means that the beautiful blueprint of the industrial park in the hearts of each C-Data employee has been implemented. Production plants, management buildings, staff dormitories… An industrial park with complete facilities and reasonable planning seems to have taken shape from this moment

The construction of the industrial park is of great significance for the company to expand its production scale and meet the demand of market growth. At the same time, it can also consolidate the company’s market position and help the company achieve its development goals. We firmly believe that with the completion of the industrial park, C-Data’s development will step onto a higher level!

Fizz technology support

Interview with Technology Support Fizz

Success comes from having a clear goal and sticking to do it day after day. Even if you do the same thing every day, you can make it different.”

Two years ago, Fizz gave up a good job offer and came to C-Data. What did this choice bring to him? Now, he changed from a nervous boy to a calm adult when he encountered problems. In Fizz, we can see a rare calm breath of a boy in his 20s. But in this calm, mixed with a Juvenile feeling of sunshine.

Fizz technology support

Jane:How long have you been here?

Fizz:I came to C-Data on July 11, 2019. It has been two years.

Jane:Did you come here as soon as you graduated? Or?

Fizz:When I first graduated, I found a job through school recruitment, but then I gave up that offer and recruited C-Data through the social recruitment.

Jane:Give up the offer of school recruitment and come here through social recruitment? What attracted you here?

Fizz:The company I got the offer was in Nanshan District. Working there, I have to commute for more than two hours every day, so even if I get off work at 6:00 p.m., it’s more than 7 o’clock when I get home. It’s too far away. And if you work in Nanshan, you will basically live in Xixiang or Gushu. I don’t know if you’ve seen the scenery of the subway every morning. It’s very scary.

In C-Data, you don’t feel so depressed. The natural environment is very good, and the air index is much better than Nanshan. Occasionally there will be a gust of wind blowing, which is very comfortable. And the subway near the company is about to be repaired. It will be more convenient to commute in the future.

Jane:You have worked here for more than two years. Do you think you have any obvious changes or growth?

Fizz:I think the first is the change in ability. When I first came here, my professional ability was not very skilled. After the training of more than two years, I can handle most of my work with ease now.

Then, there are some changes in personal mentality. When I first came here, if I encountered a difficult technical problem, I would be nervous. But now when this happens again, I will calmly think about how to solve it.

When you encounter more and more technical problems, you will become more and more calm. Because at the beginning, you are a person who has never seen any technical problems, so you will find it difficult to encounter problems, but when you have experience,  you will have a feeling of analogy.

Jane:What do you think of the job of technical support?

Fizz:Generally speaking, I feel that technical support is a bit like customer service, a customer service who understands technology.

But looking further, technical support requires many abilities. It needs to communicate with sales, R & D and customers. It is a bridge, and I think this role is irreplaceable. For example, in case of a technical problem, if the customer asks the sales directly, the sales often doesn’t know what happend, because he doesn’t understand the technical problem. Conversely, the sales feedback the problem to us, we will collect information, classify it, and then transfer it to R & D for analysis and solution.

Jane:If you want to be an excellent technical support, what core competencies and qualities do you think you need?

Fizz: You have to develop some basic skills, such as English communication and document editing.

We need to write some instruction manuals and test reports in our work, so our language expression ability need to be great. If your expression is not accurate enough, R & D and sales can’t understand what you say, and everyone will spend more time on communication, which will be very troublesome.

Also, I think we should have a good attitude. Because sometimes customers are anxious when they encounter problems, they will even say some angry words, such as I want to return the goods, or I won’t buy your company’s products any more. In this case, you can’t be confused by the customer. Because the customer is concerned about whether you can help him solve the problem. You should pay more attention to his problems so that his emotions can be calmed.

Fizz C-Data technology support

Jane:Have you ever encountered anything particularly difficult at work before?

Fizz:When you do a test, you find many problems, but the timeliness of R & D to solve the problems can’t keep up, and the customer has been urging, which is very difficult.

Also, it is difficult to locate the root of the problem. You know this phenomenon is happening all the time, but you can’t find the reason.
Jane:When these problems occur, how will you solve them?

Fizz:First of all, if this is my first contact with the problem and I don’t understand it, while talking about R & D, I will also learn the relevant knowledge and see what help I can provide. At the same time, I will also refer to past successful cases to make some attempts.

Secondly, it is necessary to use all resources that can be urged to reflect the importance of this issue. Because sometimes the R & D schedule is very full, they will give priority to solving the most urgent problems. If your problem doesn’t reflect the urgency, they may lag your problem a little.

Jane:Have you ever met anything impressive or happy in your work before?

Fizz:I will be very happy when I solve the problem by myself and no longer need R & D to do more. Or I provided a good idea to let R & d know where the root of the problem is, so I will be very happy.
Jane:We have different customers all over the world. Will such geographical and cultural differences affect your work?

Fizz:Generally speaking, everyone in the technical support group only talks about technical problems. We only focus on where and when to solve the problems. There is little communication outside of work. Occasionally, we will ask about your recent situation or epidemic situation, and whether your company has any new products.

Jane:I heard that your department has a tutorial system. What do you think of this system?

Fizz:I think the tutorial system is quite necessary. Because when a newcomer enters the company, he may not understand anything. He need a person to provide him with some help or reference.

Secondly, the tutorial system can also help newcomers better integrate into us. Because his mentor gets on well with us. He knew us through his mentor, and the whole relationship network was established, and the atmosphere was gradually harmonious.

Jane:When you first came here two years ago, you were led by someone. Now you are also leading newcustomer. How do you feel in the process from getting help from others to helping others?

Fizz:Let me start with what I learned from my mentor. My mentor helped me a lot.

When I first came here, I would ask him directly every time I didn’t understand any problems. I wouldn’t check some information first. And he will tell me that you should develop the habit of independent thinking. When you confirm that you really don’t understand it, ask others. This is a polite question, because if you have been asking that kind of relatively low-level questions that can be found easily, it will disgust others.

In addition, before you ask a question, you should first think about how to ask.

Furthermore, my tutor have his own notes when he studies and works, he will give his notes to me. When I work and see that he has met this problem, I will avoid it. If I encounter new problems, I will also improve his notes and give them to the people I lead, which has a feeling of passed down from generation to generation. Your notes will be invincible if many people improve them together, because it basically includes everything, and it is of great reference value.

In fact, I feel guilty for my apprentice, because to be honest, I only worked for two years. I don’t think I’m better than him. But if he asked me a very low-level question, I would also tell him that you should think about it yourself. You can’t rely on me for everything.
Jane:In fact, I don’t think so. Since your leader let you lead the newcomers, it show that you have the ability. In other words, for these newcomers who have just entered C-Data, they may be ignorant, and you are like a senior with two years of work experience. They need you.

Fizz:Yes, you have a point.

C-Data technology support

Jane:When you think about how much better you are than them, how can you handle this emotion? You will improve your ability? Or?

Fizz:My main goal is to read more questions, because there is no end to this. Many new problems you have never seen before. You can’t say that you have traversed all kinds of problems after working for two years.

So personally, My doubt is actually an inspiration to myself.  I hope I have been asking myself what I can learn and what I can provide for others.

Here, I believe in a saying that “Success comes from having a clear goal and sticking to do it day after day.” Even if you do the same thing every day, you can make it different.

Jane:So your attitude doesn’t mean that you don’t have the ability to lead new customer, but a way of thinking that inspires yourself.

Fizz:Yes. I will share my experience with them without reservation, but I still have the same high requirements for myself. I won’t be complacent just because I know a little more than them now.

Jane:Do you have any plans for your short-term or long-term future? For example, you also mentioned that you are leading newcustomers. Do you want to develop at the management?

Fizz:I still want to deal with technology now. Science students will feel more comfortable when they engage in scientific research or technology related job, and then it’s a little hard to get along with people.

I may find it more interesting to deal with people in the future. But anyway, in the early stage, I must learn technology first, so that if there is a management post for me in the future, I can better arrange it..

Jane:Therefore, whether you want to become a professional technician or an excellent manager, there is nothing wrong with laying the foundation of technology in the first few years of your career.

Fizz:Yes. I just graduated for two years. At present, I mainly do a good job in the current technical work, constantly learn and accumulate other skills, improve my comprehensive quality, and prepare for my future career development.


C-Data 12th anniversary

C-Data 12th anniversary, thank you for your support!

Introduction: Do you know what the number “12” means? In Chinese traditional culture, 12 is a lucky number. It is the ancients’ understanding of the law of nature, the movement of sun, moon and stars and the relationship between human daily life. A year has 12 months, and 12 years is a Zodiac cycle. For Chinese people, every 12 years from birth is the year of life, which is a key year on the road of life. Fortunately,this year marks the 12th anniversary of C-Data’s founding. A new and growing road is unfolding in front of us.

On August 19, 2021, Shenzhen C-Data Technology Co., Ltd. grandly held the 12th anniversary party with the theme of “going through hardships for 12 years and working together to create a better future” at Yaduo Hotel, Shiyan innovation valley.

c-data 12 years

First of all, Mr. Alan, chairman and general manager of the company, made a speech. Mr. Alan affirmed and praised the excellent achievements made last year, and defined the company’s development goals for the next year. Among them, Mr. Alan encouraged everyone: I hope you can improve your work efficiency and work quality with a new face, so as to promote the overall development of the company and create higher achievements and a better future.

C-Data General manager

Later, during the dinner, everyone enjoyed delicious food and participated in games.

On the stage, games let everyone relax. When playing games, whether you are a leader or an ordinary employee, you return to innocence. Everyone is equally lovely, equally happy, and the atmosphere is harmonious, which makes people feel that they are back to the school days.

During the banquet, everyone clinked  glasses with exclamations of happiness to others.

C-Data Anniversary dinner

What makes people warm is that this is not an invitation party for someone, but a party that really belongs to everyone here. Why? It can be seen from the wine preparation. Whether it’s fragrant tea, refreshing drinks, or a mild beer, sweet fruit wine, or even a cup of strong Baijiu, everyone can find their love here. The preparation of drinks reflects the company’s respect and love for all employees.

Like these different drinks, each wine has its own unique charm, and everyone also has his own unique value in the company. The reason why C-Data can increase its sales performance year after year must be the support and efforts of all colleagues. Here, We sincerely say to you: Thank you! You’ve been working hard!

As the ancient Chinese poem said:“Thirty years: rank and honour, just so much dust; Eight hundred leagues: travelling with the moon and clouds.” Under the epidemic, the development of many enterprises is difficult, but C-Data has always moved forward steadily. With the joy, only when we work hard together and continue to climb bravely can we usher in the next better twelve years. Twelve years of trials and hardships, work together to create a better future. I hope C-Data will be more wonderful because of you in the next twelve years!

Logically speaking, participating in well-known exhibitions in the industry and exchanging industry experience with peers and customers is originally an attractive job that people look forward to.However, in the past two years, affected by the epidemic, many exhibitions could not be held as usual, or even postponed or cancelled. For example, GITEX 2020 in Dubai, originally scheduled in 2020, was postponed to October 2021, the exhibition sviaz2020 in Russia has not been held yet, and ANGA COM in Germany has been changed from offline to online.

The news that various exhibitions have been postponed or cancelled makes people depressed, but fortunately, there is CIOE, which has been held as usual for two consecutive sessions from last year to this year.

With the feeling of eagerness to discuss and communicate with you, C-Data cherishes this exhibition opportunity very much.

cioe 2021

In 2021CIOE, C-Data’s booth is in hall 4-4B53, and we have already finished the preparation of exhibition design. It is expected that C-Data have also brought new products such as switches, optical transmission and private cloud storage in addition to previous xPON(OLT,ONU) products, EOC,WiFi Routers, HFC(EYDFA)and other products. Each new product has its own characteristics.


Switches have not only many ports but also independent channels to isolate conflicts.Business and industrial switches can meet the needs of enterprises and individuals, as well as some special industries, such as transportation, power, security, industrial manufacturing and other different scenarios.

DWDM wave division transmission have the characteristics of single optical fiber bidirectional transmission, simultaneous transmission of signals of different wavelengths, multiple networking modes, and support multiple services.

T&T H2 private cloud storage is safe, reliable,and convenient. It is an essential data stewardship for our family.

In addition, there are many wonderful things to meet you in 2021CIOE. Considering the fact that some international customers and peers could not reach the exhibition site due to the epidemic, We’ll follow up on the show live on social media like facebook, linkedin through pictures, videos and articles.

Next-Generation PON technology War 25G PON VS 50G PON

Next-Generation PON technology “War”: 25G PON VS 50G PON

The PON (Passive Optic Network) is the emerging avenue for the digital tussle for the stakeholders. Several high-tech giants battle with each other in fields like 5G and broadband. It is worth mentioning that the two tech giants, Nokia and Huawei, have come face to face, locking horns with each other in the battlefield of broadband. Here let’s take a look at this heated topic.

Next-Generation PON technology War 25G PON VS 50G PON

25G PON by Nokia VS 50G PON by Huawei, which is better? 

Nokia favors 25G PON compared to Huawei that supports 50G PON. On the one hand, Huawei has launched a 50G PON prototype, they think that the 25G PON can not meet the bandwidth requirements and is unnecessary. Chinese manufacturers, led by Huawei, together with some South American enterprises, are in favor of 50G PON. They believe that it will bring much convenience and opportunities to them.


On the other hand, Nokia claims to launch the world’s fastest 25G PON technology with the help of Proximus, a digital communication company in Belgium. One of the fixed customers of Nokia claims that he is super supported for 25G PON. He had established long-term cooperation with Nokia since the XGS-PON system, also known as 10 G PON, was considered the latest technology globally. In its fight with Huawei, Nokia won the support of many industry leaders who are currently reluctant to jump to 50G PON directly, claiming it as a much more advanced technology, which can only be a reality in the future.


The features of the Passive Optical Network technology

Disparate people hold different opinions toward this heated discussion. It is hard for us to draw a conclusion. However, we cannot deny that the ever-increasing user demands have increased the need for the Passive Optical Network accessing. This type of internet reduces the internet budget while increasing the speed exponentially. Here we will introduce the features of the PON(passive optical network)  technology to help you figure out why it is so popular.


As PON technology is a point-to-multipoint structure, which means a single fiber optic will facilitate multiple users, the installation cost is also reduced manifold. As no electricity is used in transmitting data on the PON network, this technology is free from electromagnetic interference, resulting in no signal loss. Due to its unique structure, PON technology is a scalable solution, which is a big win for businesses that would not need extra investments while scaling their business up.


The transmission process of the PON technology

As mentioned above, the PON technology is a point-to-multipoint system that needs only one optical fiber to distribute the internet to several users. And the PON consists of three parts, and they are OLT, ONU, and ODN. The Optical Line Terminal (OLT) is a carrier device that assigns upper-layer service network data to users. At the same time, Optical Network Units (ONU) are devices on the user side that receive data from the OLT and directly provide services for users. Also, the Optical Distribution Node (ODN) is the network between the OLT and the ONU and is responsible for the transmission channel of optical signals.


olt onu odn

As it is a point-to-multipoint system, one OLT is used while the number of ONU may vary from case to case. A single optical fiber is attached with the splitter that splits the fiber bandwidth and distributes it among ONU or the end-users. As both the downstream and upstream traffic are necessary for any internet service provider, the PON technology uses different wavelengths to simultaneously proceed with the downstream and upstream traffic. This way, a seamless operation is possible without any systematic hurdle.

The differences between 25G PON and 50G PON

Although 10 G PON is a widely used technology these days, the pursuit of 25G/50G PON has made the future speedy and internet-driven. However, there is still something different in these two PONs. They mainly include the following:


  • The downstream speeds of 25G and 50G PON are 25G bps and 50Gbpstransmission rates over a single wavelength , respectively.
  • 50G PON Viewpoint: A25 Gbps upgrade step would be considered too close to 10 Gbps and so not sufficiently future proof and, hence, wasteful of the huge investment by network operators in FTTH deployment. 100 Gbps would be nice to have, but this is currently considered too challenging when considered from the whole PON industry perspective. Weigh the pros and cons of technology and requirements, it should select 50G PON.
  • 25G PON Viewpoint: 50G will require a number of new technologies, and the industry is at least 10 years away from 50G PON maturity. That is just too long a wait for broadband operators.
  • Standard:  ITU-T 50G PON standard have released G.9804 (also referred to as HSP – Higher Speed PON) .  Nokia has marched 25G PON outside ITU and set up what is now called the 25GS-PON MSA (for multi-source agreement) Group.
  • Both 25G PON and 50G PON can coexistence with GPON, XG-PON, XGS-PON, and 10G EPON, support  PON evolution and upgrade.

The applications of 25G PON and 50G PON

It is acknowledged that the 50G PON may have more applications with its higher downstream speeds and transmission rate. The 50G PON technology will be a big win for enterprises, which are in pursuit of rigorous connectivity among all their branches and cloud services through private lines. In the data revolution and the emerging Artificial Intelligence technology, the need for continuous high-speed bandwidth can only be fulfilled with 50G PON services.


While 25G PON, on the other hand, applies to mobile transport services and business sectors that need technology beyond 10 G PON urgently.

Final words

Though there is a heated discussion between 25G PON and 50G PON supported by Nokia and Huawei, it is tough for us to figure out which is the best. However, they all represent the speed at which the internet is spreading faster than ever. It is a positive signal for our humans.




Interview with Molly|”Dream about leaving job, I woke up so sad.”

“Dream about leaving job, I woke up so sad.” This is probably the most touching love story I have ever heard. However, this love story was spoken by Molly of the sales department to C-DATA, the company she had been with for 7 years.

C-DATA was established for 12 years, but she has been in the company for 7 years. In the past 7 years, what obvious changes have been made to C-DATA? As a veteran employee, how have she grown during the 7 years at C-DATA? Let us listen what she said.


He: How long have you been to C-DATA?

Molly: I have come to C-DATA for 7 years, and I joined at the end of 2014.

He: You have been here for 7 years, do you feel any changes in C-DATA?

Molly: I think C-DATA has changed a lot in the recent years.
The increase in the number of employees is the most intuitive change. When I joined C-Data, my job number was 107. There were 50 or 60 people at that time. But up to now, there are  six hundred people in company. Of course, not only the increase in personnel, we also have branches in various places, including our sales, which are also increasing year by year.

He: I’m very curious, what makes you stay here for 7 years?

Molly: I have a soft spot for C-DATA.To be honest, when I joined the company, the company was still a small company with few staff, but everyone was very friendly and got along like family. Especially in the first two or three years after I came here, I was really happy. I would involuntarily work overtime every day after get off work. The atmosphere in the whole department was very good.

Later, I clearly felt that the company was growing faster and faster, and we ourselves had grown a lot. I remember that I had a dream once before that I was leaving my job. I was so sad.


He: Why did you think of doing sales in the first place?

Molly: Actually, when I first graduated, I was a software engineer because I majored in computer science at university. But after doing it for a year, I found that I don’t like to deal with machines all day long. I am a more lively and cheerful person, I like to communicate with others. So I chose the job of international sales, and I have been doing it for seven years.

He: What is the main content of your daily work? Tell me about your state of a typical working day.

Molly: Normally, our focus will be on communicating with customers. After I arrive at the company, I will start to contact customers, such as online communication, email, video conference, and phone calls.

Then there is some other time, I will deal with some internal affairs of the company, such as a process for customer orders, and some product and software customization. You have to communicate and coordinate with various departments.
He: What about technology? You should be familiar too, right?

Molly: Yes, as a sales, you have to be very familiar with your own products before you sell them to customers.

Because I studied engineering at university, it will be a little faster to get familiar with these technical and network aspects. But if a customer asks a more in-depth technical question, I will pull a group to bring our technical support or research and development colleagues into it, and we will communicate together. Therefore, teamwork is very important. It is the joint cooperation of sales, technical support and R&D to serve customers.


He: In addition to the aforementioned, do you think you have any areas that you need to improve?

Molly: There are too many areas for improvement. It’s not just sales, I think as a person, you have to learn to live and learn.

Like we are doing international sales, many people may think that English is the most demanding. But like I have been doing it for so many years, I think English is not the core of being a international sales. Because no matter which country you do business with, the way is same. English is just a tool. What is important is your basic quality in all aspects. You need to have a certain understanding of the local culture of different countries.

He: Boss Alan and your sales department often hold meetings or do some training. Do you think this kind of training is helpful to you?

Molly: Very helpful. Because our sales are mainly to know more about the situation on the customer side, but Boss know the supply chain,R&D,of C-Data. He share the information with us. In turn, we can also share information with customers. On the other hand, the boss will analyze the PON market with us, the supply of the PON chipset, or COVID-19 Pandemic, their influence over markets. It will also give us some inspiration. I think it is quite useful.
Through these conferences and training, we have obtained a lot of cutting-edge information.

He: Have you ever encountered anything in your work that made you feel particularly fulfilled?

Molly: I think the most fulfilling thing is that the client places a big order. When I signed this order, I am very happy! happy weeks!
When we have some technical problems with our customers, we worked hard to solve the problems. Then I will be very happy,just like taking an order.

He: When you did this job, did you get anything? Or have you lost something?

Molly: I don’t think I have lost anything,but I got a lot of things .

After working so many years, I found that when you do a job, if you feel that going to work is a happy thing , it proves that you like this job very much. I am very happy every day.

He: Do you have any plans for your future?

Molly: On the one hand, I hope that my annual sales will grow in a certain proportion; on the other hand, because I am already a mother of two children, I will try to balance work and life.

Exclusive “C-DATA Factory Tour and Training Tour” for fresh graduates

It is the rainy season of one year, the outdoor typhoon roars, the lightning flashes and thunder, the indoor warm and calm, C-DATA welcomes a group of outstanding fresh graduates. In order to let the fresh graduates who are new to the workplace better enter the working condition, on July 6, 2021, C-DATA arranged a “C-DATA Factory Tour and Training Tour” specially for these graduates.

cdata factory

This visit covered the entire process of a product production, including programming, welding, testing, streaming, packaging, delivery and so on. In just one day, we witnessed the whole process of the company’s products from being made into products from small parts to complete packaging and out of the warehouse.

During the whole visit, the most impressive part was welding.
We all know that every operation link in the factory must be extremely careful and cannot make mistakes. This wave soldering link can be regarded as the most vivid embodiment of this feature. The original imagination of welding is to put two things together and weld them together. But I did not expect that the control of time, temperature and other influencing factors are extremely strict. For example, the control of time is accurate to the unit of second. The seriousness is outrageous.


Secondly, the packaging process is more impressive. Here, we found that some products will be “specially treated” and filmed and bagged, but others are not. Why is this? In this regard, the person in charge explained: Some products sold abroad will take a long time to transport, and sometimes they have to be transported by sea and other transportation methods. Filming and bagging during packaging can play a good role in preventing moisture. And some products do not carry out this operation because these orders do not have long transportation time or moisture problems, reducing the steps of film forming and bagging, can practice the concept of environmental protection and energy saving, and avoid unnecessary waste of resources.


Seeing this, a few large characters on the entrance of the second floor of the factory came into my mind again:“there are promises, principles, and rules”. For every C-DATA person, this is by no means empty words. Everyone actually uses actions to interpret the inner meaning of these big characters.

So, what do the young saplings feel after seeing so much? Did they gain anything during this visit?

First of all, let’s take a look at the visit notes made by our classmates from the Technical Support Department.


Seeing this note with pictures and texts, do you also think that this must be a college tyrant who has a serious attitude and loves to learn? This seriousness is probably… the basic qualities of being a schoolmaster?

Of course, in addition to taking out notebooks to take notes and learn knowledge, everyone can’t help but sigh: The gain from this visit is really great!

cdata factory

R&D Department-Lin Xiangyu: This visit resolved many doubts in my college days. In the university class, they buy ready-made development boards, draw PCB diagrams and give them to the project, and the finished products are sent directly. I have always been curious about how the circuit board components are soldered, punched, and routed, especially how the chip patch is operated. This visit has solved these problems for me. Although I don’t make hardware, but let me see how the development board I am currently operating has gotten into my hands step by step, and it makes me feel like I have a bottom line.


Technical Support Department-Xian Yanzhao: In general, this “factory tour” can be regarded as a pavement for my future work. For the work of technical support, if you want to grow better, you must not only have a solid theoretical foundation, but also know how to use it flexibly, and have the ability to “encounter problems and solve problems”. At the same time, it also made me understand: everyone is a powerful individual, and every job has its meaning. I will work hard to learn more knowledge, enrich myself, consolidate myself, perfect myself, and lay the stepping stones for serving customers well in the future.

pcba test

Technical Support Department-Peng Wei: When I stepped into the gate on the second floor of the factory, the entire production process of ONU and OLT unfolded before my eyes like a picture scroll. Later, I went to the first floor and learned about the plug-in, wave furnace and test packaging.

The visit of the entire SMT production line made me sincerely thank the workers and complex and sophisticated machines who worked hard in the factory. It was their hard work that allowed the ideas of the R&D department to be made into products, and then mass-produced, and then brought them to the company. Actual sales benefit. At the same time, I also saw a lot of industrial equipment that I had never seen in textbooks before, and I saw the whole process of a product from production to final packaging.

Science and technology are primary productive forces. As new young people in the new era, we have the responsibility and obligation to work harder, shoulder the important task of rejuvenating the country through science and technology, and exploring the peak of science.

Technical Support Department-Mao Liting: From this experience, I understand a truth: only by combining theory and practice can I have a more thorough understanding of knowledge. Learning the knowledge in books is to use it in practice, sum it up in experience, and improve one’s own skills and practical experience. In the future work and study, I will pay more attention to the combination of theory and practice. In addition to consolidating my professional knowledge, I also need to improve my comprehensive ability and make continuous progress and growth.


Technical Support Department-Liu Jialin: Through this visit, I have a clearer understanding of the company’s products. From R&D to finished products, there are many people’s contributions. I also find that I need to study harder and make persistent efforts in the future.

Through these feelings of everyone, we can also see that everyone has benefited a lot from this visit.

“A strong young man makes a country strong, a young man progresses, a country progresses, and a young man is strong on the earth, and the country is strong on the earth.” A few years ago, Mr. Liang Qichao said in his “Young China”. The development and growth of young people is extremely important to the development of a country. Looking at your side, the future and development of C-DATA will also be in the hands of everyone who has just stepped into the door of C-DATA. I hope that every little “you” can find their own value here, shine and become a better self, thus creating a better C-DATA.

There is another CPON, besides EPON and GPON xpon

There is another CPON, besides EPON and GPON

There is another CPON, besides EPON and GPON

CPON? You must be familiar with EPON\GPON, but do you know what is CPON?

CPON:Coherent PON.

CableLabs recently launched that project – dubbed Single-wavelength 100G PON.

What is the difference between this CPON and the traditional PON?

CPON is like traditional PON:Passive optical distribution network,Point-to-multipoint topology. Yet, CPON is different: Uses coherent modulation and detection instead of IM-DD ,Optimizes optical power distribution,Provides longer reach & higher split ratio with improved power budget, Enables 100 Gbps and beyond data rate (per lambda)…

Where can this CPON be used?

It can be applied to optical access networks such as residential broadband; wireless transmission such as midhaul and fronthaul; optical fiber to enterprises and multi-residential units…

knittle, vice president of cablelabs, believes this is the future development direction of PON. But what will happen in the future? let us wait and see!
It’s interesting to follow the development of technology. In the next article, I’m going to talk about Nokia 25g PON vs        Huawei 50G PON.

Character Interview | Li Honglin: C-Data is ready to face changes

From May 28th to 30th, 2021, CCBN2021 officially held in Beijing. As a well-known exhibition in the radio and television industry, industry insiders pay much attention to it. Today, we invited the invited guest of the exhibition: Li Honglin, the executive deputy general manager of C-DATA, to talk to us about the experience of this trip.

11. After participating in this CCBN2021, what is your deepest feeling?

【The industry has entered a bottleneck period. Under this circumstance, who can adapt to the changes and find new product and business directions, who will usher in new opportunities; the living space of traditional enterprises that follow the old fashioned and unprepared will be narrowed】

In CCBN2021, some familiar small and medium-sized enterprises unexpectedly did not come to the exhibition, indicating the bottleneck of the industry and the differentiation of enterprise development.

CCBN is mainly an exhibition in the radio and television industry, while the traditional radio and television market is based on the province as the smallest operating network, unlike China Telecom, China Mobile, and China Unicom, which are operating systems that are one network across the country. In the past, small and medium-sized enterprises still had opportunities. However, as the operating investment of provincial-level radio and television network companies slowed down, the living space and market opportunities for small and medium-sized enterprises were significantly reduced. From the perspective of budget control, many companies at this exhibition did not come.

At the same time, when the Ministry of Industry and Information Technology issued the 5G license, it also issued a 5G license to China Broadcast Network, which is building a nationwide network, which is often referred to as a 700MHZ 5G license. This is a good opportunity for the original telecommunications and mobile equipment suppliers, especially leading companies such as Huawei and ZTE. They want to transplant their capabilities, business models, and products from telecom operators to broadcasting and television. However, since it is still in the early stages of development, there is still a period of in-depth discussion on specific issues such as how to build the network, how to cooperate, and how to proceed with the next step of market promotion. Judging from the importance attached to this exhibition by companies such as Huawei and ZTE, they should be making advance arrangements.

For small and medium-sized enterprises, it is either to withdraw, or to make a breakthrough, or to shift to differentiated market segments. C-Data’s subsidiary Wuxi Leihua, which is in charge of domestic radio and television, won bids in many provinces and cities across the country in 2020, which shows that we have the ability to make breakthroughs. At the same time, we are also engaged in optical transmission DWDM products, smart city products, home network products, etc. Multiple market segments are advancing side by side, digging deeper into demand and expanding the living space.


2. What impact do you think the epidemic has on this exhibition and the development of the industry?

【The epidemic has a great impact on the exhibition and the industry】

The epidemic has a greater impact on this exhibition, because travel is restricted during the epidemic, and considering safety reasons, the number of customers who come to the exhibition is less than expected. But for all customers who can be there, we can find some excitement to conduct in-depth communication and discuss opportunities for follow-up cooperation. In the past, many international customers came to the exhibition. This time due to the epidemic, international customers were unable to come to the exhibition. For customers who are unable to be present, we try our best to communicate through voice and video chat tools, which not only introduce the exhibition situation but also collect market demand.

The impact of the epidemic on the development of the industry is different at home and abroad.

The domestic epidemic is well controlled, so the impact on the industry is not much felt, and the overall market is stable. However, due to the epidemic in foreign countries, the demand for broadband access, broadband lines, and expansion of transmission bandwidth has increased rapidly, so the market demand for broadband network equipment is increasing.

The epidemic has had a major impact on the entire upstream supply chain. The shortage of chips and supporting materials and the increase in prices are a huge test for communication equipment manufacturers. Some companies with small size, weak anti-risk capabilities, and poor supply chain management capabilities will fall behind. Due to the advance judgment of the situation, C-Data has maintained the stability of upstream resources in the case of material shortages in the market, and can meet the order needs of long-term cooperation value customers. However, it is difficult to meet the order delivery of some new customers and small customers. The short-term turbulence of the epidemic will not change the long-term trend of the industry, and will help outstanding companies grow bigger and stronger.


3. Are there any industry hotspots in the near future? What do you think of these hot spots? What impact do you think these hot spots will have on us?

【From the perspective of operators, the industry has encountered bottlenecks and overall revenue growth has slowed down. Operators hope that manufacturers can form strategic partnerships with them and develop markets with them.

From the manufacturer’s point of view, the manufacturer’s focus is on speed, and more consideration of C-oriented products and solutions. 】

For manufacturers, the overall market environment has changed considerably in the past 10 years and 20 years ago.

In the first 20 years, China’s communication network was relatively backward, so there was no need for equipment manufacturers to actively promote it. Operators themselves had a strong demand and driving force for investment in network construction. People also needed video, voice, broadband, and video, and the market demand existed objectively.

In the past 10 years, our equipment manufacturers have to run faster and more actively, to invent, create, and promote some advanced solutions, actively attract operators to purchase, build, and invest, and promote operators to improve their business and services. Sell to businesses and consumers. Because the highway is getting wider and wider, the revenue growth slows down for the operators, and there is no novel experience for the common people. It is nothing more than a faster speed and the cheaper the toll, the better, so the manufacturer can do it. The main thing is bandwidth acceleration, it is difficult to have killer applications like smartphones.

From a wireless perspective: switching from 4G to 5G, various needs can be extended from the different application scenarios of 5G;

From the perspective of the home: WIFI6, 10G fiber to the home appears for home access. This is the bandwidth acceleration of different application scenarios.

At the same time, there is also a need for expansion of the trunk network: now it is from 100G to 200G, and it may be 400G or even 1T in the next one or two years.

On the other hand, operators are also worried. Operators hope that manufacturers will not just promote products blindly, but from their perspective, provide more B-side and C-side solutions. The operator hopes that you can tell him that the products and solutions you provide can help him make money in which industry and market direction, and then he has a greater willingness to invest.

Because the payback period of traditional communication equipment is long, it takes about 5 years, but after the acceleration of product iteration, operators are a bit resistant and overwhelmed by the cost pressure of the bandwidth acceleration process. Therefore, operators hope that manufacturers can form strategic partnerships with them and develop markets with them.

Faced with such a market situation, C-Data will naturally not lag behind. For example, our newly established business units and subsidiaries are actively developing and promoting related products and solutions such as smart software, DWDM transmission and network security storage, rather than a simple single product status.


4. As a manufacturer of communication equipment, what advantages do you think we have?

【First of all, we have a strong manufacturing and R&D team. Secondly, being able to develop to the current state in just a dozen years shows that we have also found our own gameplay in terms of team combat effectiveness, market comprehensiveness, and supply capabilities. 】

Our main advantage lies in: We have a strong manufacturing and R&D team. At the same time, there are nearly 20 years of market and experience accumulation in the industry.

Over the years, as the unicorn companies at the head have grown larger, the growth and opportunities for the second and third tier companies have become less and less. C-Data’s ability to reach the current scale in just a dozen years shows that we have found our own gameplay in terms of team combat effectiveness, market comprehensiveness, and supply capabilities.

In terms of expansion, similar to Huawei’s early years of competing with foreign counterparts and adopting the strategy of encircling cities from rural areas, you are the leading country and operator, and I am the country and customer you did not do. Customers of different sizes will also seek the right products, cost-effectiveness and after-sales service.

But in the differentiated market segments and products, the competitiveness is actually converging, mainly depending on the strategic layout of the operators.

In fact, the operator does not want a certain equipment supplier to dominate the rivers and lakes, so that it becomes Party B commanding Party A. If the operator has a personalized demand for network reform, the need for customization is completely controlled by the supplier, so They want to be diversified.

5. As a communications equipment manufacturer, what do you think we can improve?

[Own original product improvement, brand building, product line diversification]

First of all, it must be the improvement of its own original products, so there is no need to say more about this.

Secondly, it is brand building.

In fact, the communications industry has changed from a high-tech industry to a basic industry. With the increase of capacity, the accumulation of products and technologies, there is a process of transforming cocoons into butterflies from quantitative changes to qualitative changes, rather than simply saying that he can do what I cannot do. That is to say, my current ability and level are there, but my brand is not as good as yours. I cannot reach the comprehensiveness of my market layout and product solutions. Therefore, brand building is particularly important.

Finally, the product line is diversified.

There is now such a trend: the original leading companies in the communications industry or the leading companies of large IT companies are using their original R&D capabilities and manufacturing capabilities to move toward smart terminals, home appliances, enterprises, and related software. Hardware extension, plus one’s own understanding of a certain type of product, to cross-border.

A typical example is the success of the Internet industry. It is equivalent to saying that the operator is making the road wider and wider. He is a road repairer and we are a provider of sand and gravel cement. However, the operator only earns tolls. Then who builds the cars on the road? Who makes more? Therefore, try to diversify your product line as much as possible.

TR069 Protocol or WAN Connection, Which is Better?

TR069 Protocol or WAN Connection, Which is Better?


The rapid development of information technology and extensive use of a large number of terminal access devices are challenging the types, volume, and scale of services carried by PON (Passive Optical Network). The increasing service of PON requires effective management for the customer premises equipment.

We learn from the previous article titled Differences between HGU ONU and SFU ONU that OLT configures and manages ONU through OAM / OMCI. There is a one-to-one mapping between the GEM port on the WAN side and the UNI port on the LAN side in SFU ONU, so OLT can control each port and monitor the traffic of the ONU.

However, OLT fails to remote manage the HGU ONU due to that the data docking between OLT and ONU is through VEIP whose tasks nevertheless are configured by ONU itself, which is unacceptable for the gateway type ONU terminals widely used in the network of operators.

Management mode based on the TR069 protocol and the development of WAN connection based on private OMCI is two solutions applied to the remote management of ONU, facilitating the business distribution and saving the maintenance cost of operators.

The rest of this article will focus on the introduction and applications of the TR069 protocol and WAN connection configuration.

  1. TR069 Protocol

TR069 short for “Customer Premises Equipment (CPE) WAN Management Protocol (CWMP)”, is an Internet Protocol developed by DSL forum suitable for remote management of CPE. As the document number used to carry the protocol is TR069 in the DSL forum, it is referred to as TR069 protocol.

1.1Management Mode of TR069 Protocol

The management server, such as ONU, in the management mode defined by TR069 protocol, goes by the name of the Auto-Configuration Server (ACS) that is responsible for the management of Customer Premise Equipment (CPE). The interface between ACS and CPE calls the southbound interface, and the interface between ACS and other network management systems, service management systems, and billing systems (OSS / BSS) of operators is the northbound interface. While TR069 protocol mainly defines the standard of southbound interface and allows ACS to provide services to a CPE or a group of CPEs based on multiple standards.

Figure 1.1 Management Mode of TR069 Protocol

1.2 Functions of TR069 Protocol

TR069 protocol describes a mechanism that builds a safe framework of automatic configuration and management for CPE by ACS and adds the management function of CPE to this framework. The purpose is to manage a CPE or CPE collection by achieving the following functions.

1.2.1 Auto-configuration and dynamic services provisioning. The parameters involved in the mechanism include both general parameters and user-defined parameters (such as WAN connection, Wi-Fi, voice, etc.), leaving more independent space for software implementation.

1.2.2 Software and firmware image management. Downloading and uploading files are available for CPE. The protocol provides a method to check the software or firmware version and can process files of signature data. After the end of file transfer, ACS will be notified whether return successfully or not.

1.2.3 Diagnosis. TR069 protocol supports the generation of effective diagnostic information by CPE. ACS diagnoses and solves connectivity or service problems with this information and powers with the pre-defined diagnostic ability.

1.2.4 Alarm. Event reports are actively sent by CPE to realize real-time alarms of equipment.

1.2.5 Traversing NAT connection. TR069 protocol allows ACS to manage devices following NAT but limits initiating sessions. The mechanism of TR111 is a supplement to TR069, which enables ACS to initiate a session. CPE will search for ACS server automatically in initial installation (CPE, when it leaves the factory, is configured with a default URL address that points to ACS server). Communication and download with ACS after successful connection can achieve, and the management after NAT gateway will be perfect..

1.3 Protocol Stack Structure

The protocol stack structure of TR069 is shown in the following table:

Layer Description
CPE/ACS Management Application The CWMP protocol can be achieved by the management application on the CPE and ACS respectively. The application is defined locally but not as part of the CWMP protocol.
RPC Methods CWMP protocol defines various RPC methods to realize the interaction between ACS and CPE. The RPC method includes defining CPE parameters which can be accessed by ACS and the PRC method associated with this parameter.
SOAP Remote encode based on standard XML syntax to avoid the conflict with firewall.
SSL/TLS Standard network transport layer security protocol (optional). SSL protocol specifies a layered mechanism that ensures data security between application protocol and TCP / IP protocol. It provides data encryption, server witness, message integrity and optional client authentication for TCP / IP connection to ensure that the data will not be changed during transmission.
TCP/IP Standard TCP/IP

1.4 TR069 Session

The TR069 session begins with the connection between CPE and the TCP / IP of ACS. In the process of connection, CPE as the HTTP client sends its SOAP requests to ACS through HTTP post, while ACS as the HTTP server sends its SOAP request to the user’s device through the HTTP response. Each HTTP request can contain multiple SOAP requests or responses. Moreover, the parameter information of CPE can be configured and obtained through the set and get operations in this process. Finally, the connection closes.

To ensure the security of the management system, the TR069 protocol suggests SSL / TLS the authentication for the user equipment. The authentication method defined in HTTP 1.1 should be used if SSL / TLS is not allowed. The specific TR069 session flow is shown in figure 1.2.


Figure 1.2 TR069 Session Flow

In particular, since ACS and CPE are from different manufacturers, the node settings of ACS’s and CPE’s parameters are more or less different. There is a need for CPE manufacturers to make adjustments according to the parameters of ACS. This is the reason why we get feedback from customers that it is impossible to configure C-Data ONU through TR069 protocol on ACS.


Generally, the HGU ONU on the market, for the convenience of management, configuration, and monitoring, has to support the TR069 protocol.

2. WAN Connection of ONU

2.1 What is WAN Connection?

WAN is the abbreviation of Wide Area Network. WAN connection refers to the way a device connects to a WAN. For example, there are user-oriented interfaces, including POTS telephone interface, broadband LAN interface, WiFi wireless interface, and so on in a home gateway.

2.2 Principle of WAN Connection

In EPON and GPON, the protocols that OLT used to manage ONU in EPON and GPON are OAM and OMCI, respectively. Here we take OMCI as an example.

OMCI (ONU Management and Control Interface) is a kind of transmission channel defined in GPON standard to transmit OMCI messages by establishing a proprietary ATM PVC or GEM PORT between OLT and ONT. It is available for configuration management, fault management, performance management, and security management of ONU devices. ONT establishes the OMCI channel when registering with OLT. OMCI is a master-slave management protocol in which the OLT is master, and the ONT is the slave. OLT controls multiple ONT devices under OLT through the OMCI channel. Figure 2.1 shows the OMCI model for reference.

ONT management and control interface

Figure 2.1 OMCI Model for Reference

2.3 Analysis of OMCI Message Format

OLT and ONU interact through OMCI. GPON standard protocol defines the OMCI message format, as shown in Table 2.1:

Segment ATM/GEM Header Transaction



Message Type Device Identifier Device Identifier Message contents OMCI Trailer
Length(byte) 5 2 1 1 4 Baseling 8
2 0-1964

Table 2.1 OMCI Message Format

The explanation of each field is as follows:

  • ATM/GEM Header:Itcontains information to distinguish different GEM ports。
  • Transaction Correlation Identifier: the numericalvalue of this field should be consistent in a group of messages corresponding to requests and responses. In the Baseline OMCI message, the highest bit of this field indicates the priority of the OMCI message.
  • Device identifier: 0xA represents the Baseline list, and 0xB stands for the Extend list.
  • Message identifier: a 2-byte entity or instance ID
  • Message Contents: packet payload.
  • OMCI trailer: two bytes are packet length 0x28 and four bytes are CRC32 for Baseline OMCI message; while only four bytes for Extend OMCI.

Message Type:

  • DB (Destination Bit): it is consistently 0.
  • AR (Acknowledge Request): whether an OMCI message requires the response.
  • AK (Acknowledge): whether an OMCI message is a response.
  • MT (Message Type): supports up to 32 message types and message types 4 through 28 are defined in the protocol.

The specific definition of relevant configuration parameters of WAN connection will not be detailed here as they are defined by the equipment manufacturer in Baseline list.

As a matter of fact, there is no relevant configuration parameters of WAN connection in G984 / G988 standard. Therefore, some relevant parameters is defined in Extend list by the device manufacturers to meet the needs of users and the WAN connection becomes a private protocol of the equipment manufacturer. It throws out the requirement that private protocol of the equipment manufacturer should be available for both OLT and ONU.

3. Comparison of TR069 Protocoland WAN Connection

TR069 protocol and WAN connection differ in application due to difference of protocols. Three aspects are compared as follows:

  • Cost performance

A TR069 server has to be set up in the network if TR069 management method is applied. The configuration and operation cost of TR069 server is nothing to large-scale operators or ISPs. Moreover, TR069 can effectively solve the problem of batch distribution for ONU’s service. However, small-scale operators or ISPs prefer more economical solution as the cost of TR069 server is too high for them. WAN connection that only need to be compatible with software on OLT is the key to them, without any hardware cost.

  • Compatibility

There are compatibility problems for TR069 protocol and WAN connection due to the difference of device manufacturers and definitions. It is relatively easy to deal with the compatibility problem of TR069 protocol by providing the information of each TR069 node they need to the home gateway manufacturers for software compatibility processing.

As for the compatibility of WAN connection, C-Data sets its own private protocol to realize the configuration of WAN connection. Nevertheless, if there are third-party ONU devices in the system, the third-party ONU manufacturers requires to do compatibility development.

  • Easy to manage

Only the network between the TR069 server and the home gateway device is interoperable can the TR069 server effectively manage the home gateway and automatically configure the terminal device successfully registered on the server. There are many subnets and routers between the server and CPE, so the network is relatively complex. If the network is unstable, TR069 server will be difficult to manage the home gateway equipment. Therefore, a strict requirement is for TR069 server and its network.

It is much more convenient and easier for WAN connection to configure and manage home gateway than that of TR069 server. That is because there is only one optical fiber between OLT and ONU and no complex network structure. OLT still manage ONU even if the user’s Internet service is not available as long as the ONU is registered with OLT.

5. Conclusion

You may come to a clear understanding for TR069 protocol and WAN connection from the above introduction. TR069 protocol and WAN connection are two management methods that both can realize the remote management of gateway ONU and have their own characteristics. When it comes to which one is the best, it spends on your specific networking and requirements.
