The loss of hollow-core Nested Antiresonant Nodeless Fiber (NANF) has been steadily
decreasing lately, approaching that of standard Single-Mode Fiber (SMF). As for non-linear …

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 …

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 …

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

In this paper, we develop a general first-order perturbation theory of the propagation of a
signal in an optical fiber in the presence of amplification and Kerr nonlinearity, valid for …

A Gaussian noise (GN) model, precisely accounting for an arbitrary frequency dependent
signal power profile along the link, is presented. This allows accurate evaluation of the …

The problem of analytical evaluation of the maximum rate at which information can be
reliably transmitted on a nonlinear wavelength division multiplexing fiber-optic channel with …

A closed-form formula is derived, which corrects for the modulation format dependence of
the Gaussian noise (GN) model in the presence of inter-channel stimulated Raman …

The channel capacity of a nonlinear, dispersive fiber-optic link is revisited. To this end, the
popular Gaussian noise (GN) model is extended with a parameter to account for the finite …

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 …
