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 …

Predicting the quality of transmission (QoT) of a lightpath prior to its deployment is a step of
capital importance for an optimized design of optical networks. Due to the continuous …

To effectively operate multivendor disaggregated networks, the performance of the physical
layer needs to be assessed by a quality-of transmission estimator (QoT-E) delivering quick …

Dramatic increase in data traffic, future diffusion of bandwidth-hungry 5G connectivity and
evolving services like virtual reality and cloud will require the implementation of the open …

It is estimated that 5G and the Internet of Things (IoT) will impact traffic, both in volume and
dynamicity, at unprecedented rates. Thus, to cost-efficiently accommodate these challenging …

We study the techno-economics of submarine systems constrained by a fixed electrical
power supply. We show significant cost savings for high-capacity submarine systems using …

This tutorial paper reviews advanced modulation techniques that have been proposed in the
literature for the implementation of flexible (or reconfigurable) transceivers, which are …

Optical wideband communication systems aim at transmitting over several, if not all, of the
low-loss windows of single-mode fibre, ie the O-, E-, S-, C-, and L-band. Recently, there has …

Achieving greater transmission capacity in submarine optical cables is of great interest as
data traffic demands continue to increase worldwide. A significant constraint unique to …
