DCM Dispersion Compensation Card G.652 Optical Fiber Dispersion for SDH System.
The DCM Dispersion Compensation Module is mainly used for the optical signal long-haul transmission and to compensate for the G652 single-mode optical fiber dispersion in the long-haul DWDM communication system. DCM module can work with other function cards (such as DWDM, OADM, EDFA, and OTU)together to construct the complete optical network transmission system.
