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.
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.
