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 …

Since light-paths are the basic connections in wavelength routed networks, their effective
establishment is very important. Routing and Wavelength Assignment (RWA) techniques …

Dense wavelength-division multiplexing (DWDM) is a promising approach to design
ultrahigh-capacity fiber-optic communication systems (>\;50 Tb/s). However, DWDM gives …

A simple but accurate analytical model for the fiber-optic channel affected by cross-phase
modulation (XPM) is proposed and validated through numerical simulations. The model …

Starting from a previously proposed frequency-domain Volterra series nonlinear equalizer
(VSNE), whose complexity evolves as O (N 3), with N being the frequency-domain block …

In long-haul dense wavelength-division multiplexing (DWDM) systems with periodic
dispersion compensation and amplification, system performance is adversely affected by …

Gordon and Mollenauer, in their famous paper published in 1990, laid out how the interplay
between the nonlinear Kerr effect in optical fibers and the amplified spontaneous-emission …

This paper reviews the application of the Volterra series expansion to fiber-optic
communication systems and performance evaluation of dispersion maps. It is shown that …

In this paper, we propose a digital coherent demodulation architecture using fully
interpretable deep neural networks (NNs). We show that all the conventional coherent digital …

Previous results suggest that the crosstalk produced by the fiber nonlinearity in a WDM
system imposes a severe limit to the capacity of optical fiber channels, since the interference …
