For reliable and efficient network planning and operation, accurate estimation of Quality of
Transmission (QoT) before establishing or reconfiguring the connection is necessary. In …

The GN model of nonlinear fiber propagation has been shown to overestimate the variance
of nonlinearity due to the signal Gaussianity approximation, leading to maximum reach …

We discuss an analytical model that predicts the impact of the Kerr nonlinearity in optical
communication systems when the signal spectrum is wide and the accumulated dispersion …

In optical networks, a connection (eg, light-path and light-tree) is set up to carry data from its
source to destination (s). When the optical signal transmits through the fiber links and optical …

Recently, multi-band elastic optical networks (MB-EONs) have been introduced to increase
the transmission capacity of optical networks by expanding the transmission frequency …

By associating machine learning and an analytical model (ie, the Gaussian noise model),
we reduce uncertainties on the output power profile and the noise figure of each amplifier in …

Optical networks have historically been designed to be operated statically. Connections are
overprovisioned so that they remain uninterrupted over several (eg, 10) years, using high …

Due to the high potential of multi-band transmission (MBT) systems as a short-to medium-
term solution to the ever-increasing demand for fiber capacity, one of the recent areas of …
