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 …

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 …

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 …

We investigate via experiments and simulations the statistical properties and the
accumulation of nonlinear transmission impairments in coherent systems without optical …

An analytical discrete-time model is introduced for single-wavelength polarization
multiplexed nonlinear fiber-optical channels based on the symmetrized split-step Fourier …

By extending a well-established time-domain perturbation approach to dual-polarization
propagation, we provide an analytical framework to predict the nonlinear interference (NLI) …

Soft-decision forward error correction (SD-FEC) schemes are typically designed for additive
white Gaussian noise (AWGN) channels. In a fiber-optic communication system, noise may …

We show that the accumulation rate of nonlinearity in highly-dispersive long-haul coherent
links can also be measured from the nonlinear threshold decrease rate, and provide …

Noise due to nonlinear effects in uncompensated links has recently been shown to be
Gaussian and additive. We experimentally investigate the law governing its accumulation …

Coherent superposition of light waves has long been used in various fields of science, and
recent advances in digital coherent detection and space-division multiplexing have enabled …
