Verfahren und Vorrichtung zur Kompensation der Polarisationsmodendispersion auf Grund von der Farbenzerstreuung in einem optischen Übertragungssystem

摘要

The optical transmission compensation system has a terminal transmitter (Tx) transmitting an optical polarised signal on a fibre optic transmission line. There is a polarization control (PC) with a differential polarization delay (DDG), to a receiver (Rx). The control is placed between the terminal receiver and the transmission fibre. A feedback mechanism (CU) controls the polarization control. A second fixed value chromatic dispersion compensation (DCFO) minimizes the error.
