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

摘要

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.
