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 …

We show that system performance degradation due to in-line optical filtering by wavelength
routing nodes in WDM networks can be correctly modelled using digital communications …

The adoption of open optical networks (OONs) requires the development of open and
effective network planning tools, enabling the use of multi-vendor or white-box transport …

Resource allocation for transport optical networks has traditionally used a transmission
reach constraint to estimate physical impairments. For flexible-grid networks, nonlinear …

This chapter aims to provide a comprehensive picture of the impact of fiber nonlinear effects
on modern coherent wavelength division multiplexing (WDM) systems' performance. First …

We present a detailed statistical model of nonlinear interference noise (NLIN) in optical
communication systems. We demonstrate an efficient method of calculating second-order …

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 …

For high symbol rate fiber optic networks, the estimation and monitoring of time varying link
performance parameters are critical for delivering optimal network performance. In this …

Constraint-based routing (CBR) requires a fast and accurate assessment of the different
physical degradation effects in optical communications systems. This paper deals with fast …

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 …
