The China Academy of Information and Communications Technology is the most important research institute in the field of information and communications (ICT) in China. A lot of work has been done on the national development strategy of information communication, independent innovation, industrial policy, industry management, planning and design, technical standards, testing and certification, and on 4G/5G, industrial Internet, smart manufacturing, mobile Internet, Internet of Things, Internet of Vehicles, future network, cloud computing, big data, artificial intelligence, virtual reality/augmented reality (VR/AR), smart hardware, etc. In-depth research and prospective layout of network and information security are carried out.
On October 15, 2020, China Academy of Information and Communications Technology issued a series of white papers concerning ICT. Among them, the white paper on broadband development in China (2020) combines the measures and effectiveness of broadband development in China from 2016 to 2020, and makes a comprehensive judgment on the evolution trend of broadband development at home and abroad in the future. Based on the challenges of the new and old problems facing the development of broadband, this paper puts forward some suggestions to continuously promote the construction of broadband facilities under the new situation.
The customers of C-Data include many overseas Fix-network operators, ISPs and so on. In order to let overseas customers better understand the development trend of China’s broadband network and learn from China’s experience, C-Data has specifically translated the excerpts related to “Fixed Broadband Access Network” in the “White Paper on China’s Broadband Development (2020)” for you, hoping to help you.
The following contents are selected from “China’s broadband development white paper”:
As an “information superhighway”, the development level of fixed broadband network has become a “barometer” of the national ICT development level and one of the important indicators to measure the country’s comprehensive national strength. The global trend of accelerating the deployment of fixed network Gigabit is significant, and all countries are actively promoting the process of high-speed broadband network.
According to the data of OVUM , the penetration rate of FTTH in the world is 54% and increasing continuously. All-optical access has become the mainstream of the industry. 234 operators in 57 countries have published Gigabit business, and more than 20 operators have published Gigabit business.
North American cable service providers have a regional competitive advantage by providing access networks up to gigabytes based on coaxial cables and using DOCSIS3.0 technology. The United States developed the earliest, and most operators have introduced Gigabit business, but it is still in the stage of popularization.
European telecom operators still maintain a large number of copper wire access network and operate faster through new technologies such as Vectoring and G.Fast. At the same time, most countries have published Gigabit business, but the overall development is slightly slower in Asian countries such as China, Japan and South Korea. For example, Spain’s all-optical network plan will cover 100% of the country’s population in 2021; The German Gigabit Strategic Plan will have full Gigabit access capacity in 2025.
Japan, South Korea and Singapore in Asia started later than the United States, but they are developing rapidly and have entered the later stage of Gigabit development, with the coverage of Gigabit households in Korea and Singapore reaching 93% and 95%, respectively.In other countries, the trend of power companies (with pipeline resources and construction capacity) cooperating with operators to build all-optical access network has gradually emerged in recent years, accelerating the development of high-speed broadband.
In particular, in February 2020, the European Telecommunications Standardization Association (ETSI) established the Working Group on the Fifth Generation Fixed Network (F5G) to study the F5G standards and applications and promote the intergenerational evolution of fixed broadband.
According to ETSI definition, F5G is the fifth generation of fixed network represented by 10G PON access, Wi-Fi6 and 200G/400G transmission technology. It contains three main application scenarios: GRE (High Reliability Experience), eFBB (Enhanced Fixed Bandwidth), FFC (All-Optical Connection), and opens a new era of optical connectivity from optical fiber to home to rooms, desktops, parks, factories and even machines.
China is leading the world in the basic advantage of optical network, and is entering a new Gigabit ultra-wide stage represented by 10G PON technology. In 2019, the Ministry of Industry and Information launched the “Double G Double Tip” action, which pushes the dual fixed and mobile broadband into the Gigabit era, providing basic network guarantee for innovation and promotion of high-bandwidth applications.
Basic telecommunication operators responded positively and proposed clear plans for the development of Gigabit optical network successively. At present, Gigabit broadband access network has been deployed in more than 300 cities throughout the country, covering more than 80 million household users. Most provincial telecommunication operators have issued Gigabit commercial packages, and more than 2.7 million National Gigabit broadband access users. In just five months, the number of new users exceeded last year’s total number of users (870,000).
Beijing Mobile will accelerate the construction of F5G and create thousands of double Gigabyte boutique communities throughout the city. Guangzhou Telecom and Huawei released the industry’s first FTTR White Paper, which guarantees Gigabit broadband full house coverage through an all-optical home network solution. Hangzhou Mobile released the “Double 5G” Digital City White Paper to consolidate the solid base of the digital economy.
In the next five years, optical access networks will accelerate into the Gigabyte era. The 10G PON passive optical network technology is characterized by large bandwidth and wide coverage. A single system can provide Gigabyte access for 30-40 families, making it the preferred technology choice for operators all over the world when deploying high-speed optical access networks.
China’s Gigabit Broadband will continue to expand its coverage to achieve multi-scenario applications such as home, enterprise, business and factory manufacturing, connect a large number of devices and terminals, and provide users with stable and high-speed bandwidth access capacity. Specifically, the future construction and development of optical access network will focus on the following three aspects:
(1) Gigabit Speed Up: Targeting home Gigabit rate access, fully using 10G PON technology; Gigabit wireless local area network (WLAN) is used in home scenarios to increase the endpoint access rate and provide Gigabit bandwidth to user terminals in conjunction with 10G PON.
(2) Fibre to Everywhere: In the physical layer, the scene of optical connection extends from home to thousands of industries, including optical fiber to room, industrial PON (industrial optical network, optical fiber to machine), optical fiber to park enterprises (various types of government enterprises, parks, education, power, transportation and other vertical industries), through a new generation of high performance, high integration, Low power photoelectric chips and algorithms to ensure fast response, low latency, high reliability and safety in industrial level.
(3) Ultimate experience: Through the application of large data collection, edge computing, artificial intelligence and other technologies, plus end-to-end network slicing, multi-level scheduling and guarantee algorithm, to provide different and accurate service guarantee for different users and different businesses, and to enhance users’business experience.
Each country has different national conditions and broad development stages, but based on 10G PON as well as higher-speed passive optical network technology, which provides up to Gigabytes of optical access per household, the construction of broadband access network around Gigabyte speed-up, optical connectivity and ultimate experience is undoubtedly the mainstream development direction in the world. Gigabit access to the home and dual Gigabit access to mobile and fixed networks are currently in its infancy, and it will take at least 5 to 10 years for the experiment, promotion and popularization to take place.
According to the relevant statistics, in the current purchasing market of broadband access devices, 2.5 GPON ONU products are still the mainstay of the market and account for at least 70% of the total market share. However, in OLT products, the market share of 10G PON OLT ports is increasing year by year.
Compared with China, North America, Japan and South Korea, the permeability of optical access in Southeast Asia and South America is low. Providing GPON-based optical broadband access remains the main demand for a long time.
