The paper on the enhanced version of the GN model (the EGN model) is now available on Optics Express. The EGN model achieves excellent accuracy in predicting the power of non-linearity interference (NLI) that perturbs each transmitted channel. A version of the same paper that includes extended appendices on formulas derivations can be downloaded from arXiv: download paper with extended appendices from here. The EGN model has no limitations related to transmission format, Baud rate, channel spacing, number of channels, amplification type, span len
