Vorrichtung zur Polarisationsdispersionskompensation in einem optischen Übertragungssystem

摘要

The dispersion compensation system has a terminal transmitter transmitting optically polarized words on a fibre optic link. There is a polarization control (PC) and differential delay (DDG) with the polarization control set by a command unit (CU). The digital words are transmitted in frames with redundant words. The receiver (RX) uses the redundant words to detect errors and operate the command unit to correct the polarization errors.
