“…Many excellent papers deal with modeling the impact of nonlinearities onto the signal quality. In [6,7] an analytical model of XPM is presented, in [8,9] the FWM, in [10,11] the SRS, and in [12,13] the SBS is introduced. In our paper, we present a complete model which includes the calculation of signal degradation due to XPM, FWM, and SRS, based on the previously mentioned publications.…”
