Networks are complex interacting systems involving cloud operations, core and metro
transport, and mobile connectivity all the way to video streaming and similar user …

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 …

Several approximate non-linear fiber propagation models have been proposed over the
years. Recent re-consideration and extension of earlier modeling efforts has led to the …

The GN-model has been proposed as an approximate but sufficiently accurate tool for
predicting uncompensated optical coherent transmission system performance, in realistic …

An accurate, closed-form expression evaluating the nonlinear interference (NLI) power in
coherent optical transmission systems in the presence of inter-channel stimulated Raman …

Following the explosive growth of global data, there is an ever-increasing demand for high-
throughput processing in image transmission systems. However, existing methods mainly …

We study the properties of nonlinear interference noise (NLIN) in fiber-optic communications
systems with large accumulated dispersion. Our focus is on settling the discrepancy …

We achieved the lowest-ever transmission losses of 0.1419 dB/km at 1560 nm wavelength
and 0.1424 dB/km at 1550 nm in a Ge-free silica-core optical fiber. It was an improvement by …

A Gaussian noise (GN) model, precisely accounting for an arbitrary frequency dependent
signal power profile along the link, is presented. This allows accurate evaluation of the …

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 …
