The EM800-DCM and EM1600-DCM Dispersion Compensation modules, are part of the LambdaDriver® product line and can be hosted by the LDP300, LD400, LD800 and LD1600 chassis. The DCM is a single slot module that typically connects to the mid-stage of an Optical Amplifier, such as EM800-OAIM (Optical in line Amplifi er with mid-stage). Optical Budget is not affected if connected to OA with Mid-Stage.

The DCM provides chromatic dispersion compensation for Metro core, regional and long haul DWDM networks. Chromatic dispersion is a major distance limiting factor in DWDM networks, especially networks running 10Gb speeds. The DCM provides distance extension of approx. 80km.
