Selective Post-Compensation of Nonlinear Impairments in Polarization-Division Multiplexed WDM Systems With Different Channel Granularities

Selective post-compensation of nonlinear impairments is investigated for polarization-division multiplexed-wavelength-division multiplexed (WDM) systems. A coupled system of nonlinear partial differential equations derived from the Manakov equations is used for digital backward propagation (DBP). Three WDM systems with different channel granularities have been simulated to evaluate the performance and computational load of vector DBP when different intra- and/or interchannel effects are compensated.
