CWDM technology can flexibly increase the capacity of existing fiber optic infrastructures by enabling multiple channels / wavelengths on the same fiber optic cable. Each channel carries data signal independently from each other, which allows network designers to transfer different data rates. The CWDM technology supports applications such as 1G / 10G Ethernet, SDH / SONET and 8/4/2 / 1G Fibre Channel pass through same fiber link.
