Abstract

The robustness of polarization-mode dispersion (PMD) compensation utilizing radio-frequency feedback in the presence of polarization-dependent loss (PDL) is investigated using a closed-loop dynamic model. Simulations using mean PMD of 30% of the bit period show that mean PDL of up to 2 dB increases the Q-penalty after PMD compensation by less than 0.1 dB. We find that the compensator can become trapped in secondary optima at high PDL, incurring significant additional penalty.
