Based on TFF and AAWG technology, MUX/DEMUX making full use of the low-loss band of optical fiber, the channel of CWDM/DWDM can be combined and demultiplexed, which greatly saves the optical fiber resources, and can flexibly change the network configuration according to customers' requirements.
MUX/DEMUX is often used for long-haul transmission. DWDM system with a frequency interval of 100 GHz supports a smooth upgrade to 48 waves, and DWDM system with frequency interval of 50 GHz supports a smooth upgrade to 96 waveswhich has a higher spectrum utilization rate and saves freguency band resources. CWDM system supports a smooth upgrade to 18 waves.
