2/4/8/16/18 Channels CWDM Mux Demux, Dual Fiber, Optional Connectors and Housing

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 customized.

Wavelengths and Insetion Loss

The ITU-T G.694.2 specifies CWDM uses up to 18 wavelengths from 1270nm to 1610nm with 20nm channel spacing. But For G.652 and G.694.2 optical fiber, 1390nm and 1410nm wavelengths should be avoided due to the higher attenuation about 2dB.

Flexible Scalable Pay-as-you-grow CWDM Solutions

CWDM is more cost-effective than DWDM, but the capacity is limited. When more capacity is needed, it can be casaded one more Mux to increase the existing network capacity, and where deployment costs keeps at a minimum. Click here to see more case studies .
