Celebrating the 20^ th anniversary of Optics Express, this paper reviews the evolution of
optical fiber communication systems, and through a look at the previous 20 years attempts to …

Lightwave communications is a necessity for the information age. Optical links provide
enormous bandwidth, and the optical fiber is the only medium that can meet the modern …

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

Based on a variety of long-term network traffic data from different geographies and
applications, in addition to long-term scaling trends of key information and communication …

In order to overcome the capacity limitations of current lightwave systems based on the
single-mode optical fiber, massively parallel transmission in the spatial domain [space …

In this paper, achievable information rates (AIR) for fiber optical communications are
discussed. It is shown that AIRs such as the mutual information and generalized mutual …

In this paper, we review the historical evolution of predictions of the performance of optical
communication systems. We will describe how such predictions were made from the outset …

Through a series of extensive system simulations we show that all of the previously not
understood discrepancies between the Gaussian noise (GN) model and simulations can be …

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 …

We explore the potential benefits of digital nonlinearity compensation (NLC) techniques in
fully loaded coherent wavelength-division multiplexed (WDM) transmission systems. After …
