Abstract
We evaluate the generation of the cross-channel interference (XCI) contributor of the nonlinear interference (NLI) using split-step Fourier method (SSFM) simulations, for a variety of dispersion-managed optical links, as part of a disaggregated optical network segment. By comparing these results to the Gaussian noise (GN) model we outline the behavior of the XCI accumulation, observing that this quantity reaches an asymptotic upper bound. This quantity is observed to depend on the residual dispersion within the link, scaling with the parameters of the underlying fiber spans and the transmitted signals.
