ABSTRACT:
A technique for PMD mitigation in an optical communications system that utilizes a plurality of polarization rotators in an optical fiber to continuously rotate the polarization state of at least one optical signal that propagates through the fiber. The optical fiber is segregated into a plurality of sections and the polarization rotators are disposed between adjacent sections of the fiber. The polarization state of at least one optical signal received from the first of a pair of adjacent sections is continuously rotated by the polarization rotator prior to being transmitted to the second of the pair of adjacent sections. The rotated optical signals are collected at a receiver and corrected for errors using, for example, forward error correction.
