Xiaoping Charles Mao: Method of avoiding excessive polarization mode dispersion in an optical communications link. WorldCom, January 20, 2004: US06681081 (6 worldwide citation)

A method and apparatus for managing state-of-polarization (SOP) controllers along an optical communications link. When the polarization-mode dispersion (PMD) in the link exceeds a preset limit as determined by a PMD compensator, the SOP controller is directed to change rotation angle in an arbitrary ...
