Note: These DCMs are installed in a 1 RU, 19" LGX rack-mount housing. All DCMs use LC connectors.
Fiber Bragg Grating DCMs
Fiber Bragg Grating (FBG) DCMs can be used in the mid-stage on any of the Cyan DWDM modules
(LAD-8E, LAD-40E, L-AMP, WSS-402, and WSS-404).
The FBG models support up to 40 channels with 100 GHz spacing. They exhibit lower loss and latency than
the standard fiber-based DCMs that allow them to be used with the amplifiers included on the WSS modules
(WSS-402 and WSS-404). The WSS modules are not compatible with fiber-based DCMs due to their
excessive loss.
The FBG DCMs are housed in a 1
RU LGX shelf. A shelf supports up to three modules. All modules require
a single slot. All DCMs use LC connectors.
