CWDM 1×2
Decriptions
GEZHI Photonics CWDM technology provides the flexibility to increase capacity of existing fiber infrastructure by enabling multiple channels/wavelengths over the same fiber cabling. Each channel carries data independently from each other, allowing network designers to transport different data rates. FMU series CWDM Mux Demux covers up to 18 CWDM channels from 1270nm to 1610nm in 20nm increments as defined by ITU-T G.694.2. It's protocol and rate transparent supporting such applications as 1G/10G Ethernet, SDH/SONET and 8/4/2/1G Fiber Channel across the same fiber link.
Main advantages are its passive nature – no power supply or cooling necessary, and robustness – no special microclimate requirements, and low insertion loss – extend maximum reach of CWDM technology. A variety of wavelength combinations, port configurations and special port options can be supported, different packaging type can be customize
