The GN-model has been proposed as an approximate but sufficiently accurate tool for
predicting uncompensated optical coherent transmission system performance, in realistic …

The last few years have seen a wealth of new nonlinear propagation modeling results
appear in the literature, especially regarding coherent systems operating in the absence of …

This paper is devoted to an in-depth discussion of the Gaussian Noise (GN) model which
describes non-linear propagation in uncompensated coherent transmission systems. Similar …

The GN model of nonlinear fiber propagation has been shown to overestimate the variance
of nonlinearity due to the signal Gaussianity approximation, leading to maximum reach …

Several approximate non-linear fiber propagation models have been proposed over the
years. Recent re-consideration and extension of earlier modeling efforts has led to the …

We study the properties of nonlinear interference noise (NLIN) in fiber-optic communications
systems with large accumulated dispersion. Our focus is on settling the discrepancy …

Recently, a perturbative model of non-linear fiber propagation in uncompensated optical
transmission systems has been proposed, called GN-model [1]. Here, an extended and …

Through a series of extensive system simulations we show that all of the previously not
understood discrepancies between the Gaussian noise (GN) model and simulations can be …

We address perturbative models for the impact of nonlinear propagation in uncompensated
links. We concentrate on a recently-proposed model which splits up the signal into spectral …

The use of spectrally shaped amplified spontaneous emission noise (SS-ASE) as a method
for emulating interfering channels in optical fibre transmission systems has been studied. It …
