We investigate quality of transmission (QoT) estimation in a multi-band transmission
scenario, including a wideband description of the frequency-dependent physical layer …

Network operators are aiming to overcome the envisioned data traffic crunch by relying on
already installed fiber cables. Multiband optical line systems (LSs) will thus be the solution …

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 …

A closed-form formula for the nonlinear interference (NLI) estimation using the Gaussian
noise (GN) model in the presence of inter-channel stimulated Raman scattering (ISRS) is …

Increasing traffic demands are causing network operators to adopt disaggregated and open
networking solutions to better exploit optical transmission capacity, and consequently …

Modern optical networks depend upon advanced software-defined networking (SDN)
technologies, which in turn rely on a network abstraction to infer the quality of transmission …

We propose a method to quantitatively evaluate the improvement of the optical signal-to-
nose ratio () enabled by Raman pumping in hybrid Raman/erbium-doped fiber amplifiers …

We show how to extend the enhanced Gaussian noise (EGN) model to account for
polarization-dependent loss (PDL) of optical devices placed along a fiber-optic link. We …
