Experimental Characterization of Nonlinearity Mitigation by Digital Back Propagation and Nonlinear Polarization Crosstalk Canceller under High PMD condition
High PMD condition Digital Back Propagation Nonlinear Polarization Crosstalk Canceller
2015/5/15
Impact of PMD is evaluated on nonlinear mitigation algorithm. While the backpropagation showed consistent improvement regardless of PMD, the best performance was found under different PMD conditions d...

2015/8/3
The tolerance to PMD of 100Gb/s PDM-QPSK systems is investigated in linear and nonlinear regime.Experimental results show that nonlinear effects decrease the robustness of the system against PMD.
