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 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 …

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

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 …

This paper presents an alternative derivation of the Gaussian noise (GN) model of the
nonlinear interference (NLI) in strongly dispersive optical systems. The basic idea is to …

From first-order perturbation theory, we derive the autocorrelation function of the nonlinear
interference in coherent optical links. We show that the fundamental assumptions of the …

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 …

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 …

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 …

An accurate, closed-form expression evaluating the nonlinear interference (NLI) power in
coherent optical transmission systems in the presence of inter-channel stimulated Raman …
