Analysis of Nonlinearity Mitigation Using Spectral Inversion for Superchannel Transmission

We propose a simplified analytical model for the estimation of nonlinearity mitigation using spectral inversion. We demonstrate excellent agreement between analytical model and numerical simulations within a standard deviation of 0.2 dB Q-factor for five-subcarrier superchannel transmission over various uniform and non-uniform link configurations. The analytical model can enable fast and accurate ...
