Apparatus for polarisation dispersion compensation in an optical transmission system

摘要

The optical transmission compensation system has terminal transmitter (TX) transmitting optical polarised signals on an optical transmission line (LF). The terminal receiver (Rx) has a polarisation compensation terminal using a polarisation controller (PC). A second polarisation compensator (DCM) has adjustable compensation for chromatic dispersion so that a service control unit (CU) commands both polarisation compensation systems, using a parameter measure to optimise output quality.
