Wavelength-division multiplexing (WDM) has historically enabled the increase in the
capacity of optical systems by progressively populating the existing optical bandwidth of …

We review probabilistic constellation sha** (PCS), which has been a key enabler for
several recent record-setting optical fiber communications experiments. PCS provides both …

A transmission system with adjustable data rate for single-carrier coherent optical
transmission is proposed, which enables high-speed transmission close to the Shannon …

Different aspects of probabilistic sha** for a multispan optical communication system are
studied. First, a numerical analysis of the additive white Gaussian noise (AWGN) channel …

This tutorial paper provides a foundation for integrating probabilistic sha** (PS) and
