In elastic optical networks, digital coherent transceivers modify their symbol rate, modulation
format, and forward error correction to best serve the network demands. In a 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 …

Superchannel transmission spaced at the symbol rate, known as Nyquist spacing, has been
demonstrated for effectively maximizing the optical communication channel capacity and …

The potential to operate third-party terminals over multi-domain transparent optical networks
attracts operators and customers to implement optical spectrum as a service (OSaaS) …

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

The potential of optimum selection of modulation and forward error correction (FEC)
overhead (OH) in future wavelength-routed nonlinear optical mesh networks is studied from …

We experimentally demonstrate the lossless transmission of wavelength division
multiplexing (WDM) signals through a silicon-photonics 4× 4 switch with a flip-chip bonded 4 …

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 consider technologies that allow the throughput of fiber-optic transmission systems
(FOTSs) to be increased. The need for this is due to a growth in the volume of newly …
