System for compensating polarization dispersion of channels in a wavelength-division multiplex signal |
摘要 |
The invention concerns a system for compensating polarization dispersion of channels in a wavelength-division multiplex signal. In accordance with the invention, the system comprises a plurality of cascaded polarization control modules respectively associated with said channels and a common differential delay generator.Each polarization control module comprises a drop and insert multiplexer for extracting the signal from the associated channel from the input multiplex signal and inserting a modified channel supplied by a polarization controller.The system further comprises a control loop for controlling the polarization controllers in response to the optical properties of the channel signals at the output of the differential delay generator and obtaining a compensated multiplex signal. |
