Due to the rapid increase in network traffic in the last few years, many telecommunication
operators have started transitions to 100-Gb/s optical networks and beyond. However, high …

The design of application-specific integrated circuits (ASIC) is at the core of modern ultra-
high-speed transponders employing advanced digital signal processing (DSP) algorithms …

The FEC limit paradigm is the prevalent practice for designing optical communication
systems to attain a certain bit error rate (BER) without forward error correction (FEC). This …

Staircase codes, a new class of forward-error-correction (FEC) codes suitable for high-
speed optical communications, are introduced. An ITU-T G. 709-compatible staircase code …

The role of forward error correction has become of critical importance in fiber optic
communications, as backbone networks increase in speed to 40 and 100 Gb/s, particularly …

This tutorial paper presents an overview of advanced FEC and coded modulation (CM) for
optical communications. It describes the following ultra-high-speed optical transport …

We design staircase codes with overheads between 6.25% and 33.3% for high-speed
optical transport networks. Using a reduced-complexity simulation of staircase coded …

The capacity and geographical coverage of the global communications network continue to
expand. One consequence of this expansion is a steady growth in the overall energy …

White light generation by mixing red, green, and blue laser diodes (RGB LDs) was
demonstrated with Commission International de l'Eclairage coordinates of (0.2928, 0.2981) …

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