Vorrichtung zur Polarisationsdispersionskompensation in einem optischen Übertragungssystem

摘要

A controller controls polarization controller as a function of quality of optical signal, for optimizing the quality of optical signal. An auxiliary compensator modifies state of polarization of the optical signal if the quality of optical signal is below a predetermined level. Independent claims are included for the following: (1) compensator; and (2) optical transmission system.
