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 …

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

To support the development of intelligent optical networks, accurate modeling of the physical
layer is crucial. Digital twin (DT) modeling, which relies on continuous learning with real-time …

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 …

Equalization enhanced phase noise (EEPN) occurs due to the interplay between laser
phase noise and electronic dispersion compensation (EDC) module. It degrades …

We investigated the reach increase obtained through nonlinearity mitigation by means of
transmission symbol rate optimization (SRO). First, we did this theoretically and simulatively …

Telecommunication networks are becoming the central linking institution of the Fourth
Industrial Revolution. To cope with the associated capacity and connectivity challenges …

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 …
