Inter-Channel Nonlinear Interference Noise in the Presence of PDL

We present an analytical model which predicts the statistical properties of nonlinear interference noise (NLIN) in fiber links which are affected by polarization dependent loss (PDL). The model enables to investigate many PDL scenarios in a computationally efficient way, reducing the need to run costly split-step Fourier simulations. Using this model, we show that many features of NLIN, such as its phase and polarization rotation noise and time-varying intersymbol interference, may be significantly modified by PDL components present in the link.
