IMPROVED DISTORTION ANALYZER FOR COMPENSATION APPARATUS OF FIRST-ORDER POLARIZATION MODE DISPERSION (PMD)

摘要

The effect of polarization mode dispersion that an optical signal experience s as it propagates through an optical transmission fiber is compensated for at a receiver using a birefringent compensator, in which a distortion analyzer repeatedly examines the signal outputted by the compensator and causes the compensator to reduce the effect of such polarization mode dispersion based on the results of such examination.
