title: Interplay between PDL and nonlinear effects in coherent polarization multiplexed systems.
abstract: We analyzed the mechanism of the interplay between PDL and fiber nonlinear effects in 112 Gb/s DP-QPSK systems and showed that PDL can generate large data-dependent optical peak power variations that can worsen nonlinear tolerance and cause an additional 1.4 dB Q-penalty.
