Abstract
A polarization mode dispersion center (306) measures PMD impairment through the cross-correlation of optical pulses. A second variable phase retarder plate (504) is oriented with polarization eigenstates at preferably 45 degree angle with respect to those eigenstates of a first variable phase retarder plate (502) to provide controllable phase retardations that can be varied and measured as an indication of PMD impairment.
