Dispersion Compensation Module
The DCM/DCU is connected in series on the signal optical path. Generally, the DCM/DCU is used at the receive end for compensation, and at the transmit end for pre-compensation as required. In a non-coherent transmission system, dispersion compensation must be designed based on the fiber type and signal type to ensure that the optical signals at the receive end meet the dispersion tolerance requirements of OTU ports.
