Patent ID: 7486898

Claim:
A receiver for an optical signal containing a polarization mode dispersion-induced (PMD-induced) periodic time jitter and a time-varying distortion caused by a periodic polarization scrambled signal, comprising: at least one decision gate and a clock recovery module providing a clock signal recovered from the optical signal to the at least one decision gate, a scrambling frequency generator connected to the clock recovery module, extracting the periodic polarization scrambled signal from the optical signal, and the scrambling frequency generator is synchronized to the scrambling frequency and phase of the periodic polarization scrambled signal, a jitter function generator connected to the scrambling frequency generator which is locked in frequency and phase to the periodic polarization scrambled signal being recovered from the optical signal, and the jitter function generator generating a clock phase control signal reproducing the PMD-induced periodic time jitter, and at least one clock phase modulator modulating the phase of the clock signal according to the clock phase control signal.
