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

We review the modeling of inter-channel nonlinear interference noise (NLIN) in fiber-optic
communication systems, focusing on the accurate extraction of the NLIN variance, the …

A low-complexity model for signal quality prediction in a nonlinear fiber-optic network is
developed. The model, which builds on the Gaussian noise model, takes into account the …

The performance of digital backpropagation (DBP) equalization when applied over multiple
channels to compensate for the nonlinear impairments in optical fiber transmission systems …

For excellent cost and performance, modern high capacity transport systems use digital
coherent processing to overcome many physical barriers. Coherent methods are explained …

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 …

This paper serves to highlight the gains in SNR margin and/or data capacity that can be
achieved through a proper optimization of the transceiver parameters, for example, launch …

16-GBd BPSK bursts transported over 3× 80-km SMF with up to 12-dBm power were
successfully detected by a maximum likelihood-nonlinear spectrum detection scheme using …

Motivated by results in optical communications, where the performance can degrade
dramatically if the transmit power is sufficiently increased, the channel capacity is …

We find evidence that low-OSNR operation causes substantial penalty on the system
maximum reach due to non-linearity generated by ASE noise and due to signal-power …
