Abstract

In accordance with the present disclosure, disadvantages and problems associated with polarization dependent effects of a polarization multiplexed optical signal may be reduced through polarization scrambling. In accordance with an embodiment of the present disclosure a method for detecting polarization scrambling of a polarization multiplexed optical signal comprises receiving a polarization multiplexed optical signal associated with an optical network. The polarization multiplexed optical signal including a scrambled polarization orientation, the polarization orientation scrambled according to a scrambling frequency. The method further comprising receiving a polarization signal indicating the polarization scrambling of the received optical signal. The method additionally comprises descrambling the optical signal according to the polarization scrambling as indicated by the polarization signal.

First claim

What is claimed is:

1. A method for detecting polarization scrambling of a polarization multiplexed optical signal comprising:
receiving a polarization multiplexed optical signal over an optical network and including a scrambled polarization orientation, the polarization orientation scrambled according to a scrambling frequency, the polarization multiplexed optical signal comprising information modulated on a plurality of polarization components of the optical signal;
receiving,…
