ABSTRACT:
A PMD mitigation system is disclosed that is comprised of an interface coupled to a control system. The interface receives an optical signal and transfers the optical signal to the control system. The control system receives the optical signal from the interface, recovers a clock signal from the optical signal, optically reshapes the optical signal using the clock signal to generate a PMD mitigated signal, and transfers the PMD mitigated signal to the interface. The interface transmits the PMD mitigated signal. The PMD mitigation system advantageously mitigates PMD in the optical signal by optically reshaping the optical signal.
