In the evolution of optical networks, spectral efficiency (SE) enhancement has been the most
cost-efficient and thus the main driver for capacity increase for decades. As a result, the …

In the last twenty years, optical networks have witnessed recurrent changes in their
management and control architecture. In this paper, we present a historical timeline and a …

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

Due to widespread applications and rapid development of cloud computing and Internet
services, hyperscale data centers have experienced an unprecedented demand for …

Band division multiplexing technology is a promising medium-term transitional solution to
deal with the traffic flood, by leveraging the existing optical fiber transmission infrastructure …

In this paper, we show that by combining experimental data from different optical fibers, we
can build a fiber-agnostic neural-network to model the Raman amplifier. The fiber-agnostic …

We propose an efficient three-step amplifier configuration algorithm to improve and maintain
the generalized signal-to-noise ratio (GSNR) performance of dynamic C+ L-band links in …

Ultra-wideband transmission is a promising, cost-effective solution to meet the increasing
demand for data traffic in optical fiber systems. However, system performance and quality of …

As fiber-optic systems turn toward multi-band transmission (MBT), exploiting the complete
low loss window of optical fibers, novel optical components, able to operate in bands other …

Nowadays, the fiber spectrum is only partially exploited, ie, mainly in the C-band and more
recently in the C+ L-band, where the fiber attenuation profile experiences the minimum …
