Chromatic Dispersion Compensation Modules
EM316DCM
The EM316DCM Dispersion Compensation Modules are part of the Fiber Driver® DWDM solution. They are two-slot modules accommodated by two adjacent Fiber Driver® chassis slots. These modules may be operated as passive units in an un-powered chassis or as managed modules with an EM316LNXNM-OT Network Manager (NM) 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 protocols exceeding 2 Gbps including 2 and 4 Gbps Fibre Channel, 2.5 and 2.7 Gbps SONET/SDH OC-48/STM16 with or without FEC, and especially networks running 10 Gbps. 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 100 kilometers.
