DCM Lite Products

The DCM LiteTM product is a fixed chromatic dispersion compensation module designed  to compensate fiber span chromatic dispersion.  Inserting these modules into fiber links allows for transmission link distances to be increase past transceiver dispersion limits.

The DCM LiteTM modules are available with fiber Bragg grating (FBG) technology or dispersion compensating fiber (DCF) technology. Both technologies fit into a 1-RMU 19 or 23 inch rack mountable case.
