We review the use of optical frequency combs in wavelength-division multiplexed (WDM)
fiber optic communication systems. In particular, we focus on the unique possibilities that are …

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 …

Digital coherent transceivers have revolutionized optical fiber communications due to their
superior performance offered compared to intensity modulation and direct detection based …

Current optical fibre transmission systems rely on modulation, coding and multiplexing
techniques that were originally developed for linear communication channels. However …

Enabling the transport of fronthaul traffic in next-generation cellular networks [fifth-
generation (5G)] following the cloud radio access network (C-RAN) architecture requires a …

The capacity and reach of long-haul fiber optical communication systems is limited by in-line
amplifier noise and fiber nonlinearities. Phase-sensitive amplifiers add 6 dB less noise than …

Most of the digital data transmitted are carried by optical fibres, forming the great part of the
national and international communication infrastructure. The information-carrying capacity of …

In this paper, we experimentally demonstrate the benefit of polarization insensitive dual-
band optical phase conjugation for up to ten 400 Gb/s optical super-channels using a …

Nowadays, public demands high capacity global internet traffic in terms of cloud computing,
video gaming, fiber to the home and mobile networks, etc. To fulfill such huge traffic …

Increasing the system capacity and spectral efficiency (SE) per unit bandwidth is one of the
ultimate goals for data network designers, especially when using technologies compatible …
