PMD and PDL tolerances of transmitter-side non-linear mitigation in 112 Gb/s DP-QPSK transmission

We experimentally demonstrate that the transmitter-side non-linear mitigation, combination of non-linear pre-distortion with RZ carving is robust against polarization mode dispersion and polarization dependent loss in real-time 112 Gb/s DP-QPSK transmission over 2,000km mixed fiber link.
