OptiDriver® Dispersion Compensation Modules (DCM)
Overview
The Dispersion Compensation Modules are part of the OptiDriver® DWDM solution. They are one-slot modules
accommodated by any OptiDriver chassis slots. These modules may be operated as passive units in an non-powered chassis
or as managed modules in a powered chassis system. DCM modules provide fixed chromatic dispersion compensation for
high-speed metro core, regional, and extended-haul DWDM networks.
Chromatic dispersion is a major distance limiting factor in DWDM networks for high speed protocols exceeding 2 Gbps
including and especially networks running 10 Gbps and 100G metro direct detection solutions. The DCMs offer a high
dispersion compensation level and a very low insertion loss penalty.
They provide negative dispersion compensation over the full C-Band with possible distance extensions of up to 200
kilometers. The modules are DWDM ITU-T grided for both 50GHz and 100GHz, and slope-matched per SMF28/G.652 fiber.
