Interplay between PDL and nonlinear effects in coherent polarization multiplexed systems

We analyzed the mechanism of the interplay between PDL and fiber nonlinear effects and showed that PDL can generate large data-dependent optical peak power variations that can worsen nonlinear tolerance and cause additional 1.4dB Q-penalty.
