COMPENSATION FOR POLARIZATION-MODE DISPERSION IN MULTIPLE WAVELENGTH-DIVISION MULTIPLEXED CHANNELS

Techniques for compensating for polarization-mode dispension (PMD) in multiple wavelength-division multiplexed (WDM) channels (102) by processing all WDM channels in the same manner without demultiplexing the channels. A feedback control (136) is provided to decrease the worst-case power penalty and...

Summary:Techniques for compensating for polarization-mode dispension (PMD) in multiple wavelength-division multiplexed (WDM) channels (102) by processing all WDM channels in the same manner without demultiplexing the channels. A feedback control (136) is provided to decrease the worst-case power penalty and the channel fading probability by optimizing over the entire group of WDM channels. La présente invention concerne des techniques de compensation de dispersion de polarisation de mode (PMD) dans de multiples canaux (102) multiplexés en longueur d'onde (WDM), par traitement identique de tous les canaux WDM, sans démultiplexage des canaux. Une commande à rétroaction (136) permet de diminuer la pénalité de puissance de la pire éventualité et la probabilité d'évanouissement de canal, par optimisation sur le groupe entier de canaux WDM.
