Fiber-optic multi-band transmission (MBT) aims at exploiting the low-loss spectral windows
of single-mode fibers (SMFs) for data transport, expanding by the available bandwidth of C …

In this paper, we describe the validation of GNPy. GNPy is an open source application that
approaches the optical layer according to a disaggregated paradigm, and its core engine is …

We compare the networking merit of two possible multiplexing techniques on top of
wavelength division multiplexing to enlarge transmission capacity: the band division …

A spatial channel network (SCN) is a novel optical network architecture targeting the space
division multiplexing (SDM) era where the optical layer is explicitly evolved into the …

Optical line interface technology has been the key enabler to reduce the cost per bit
transported, thus cost-effectively scaling optical transport networks and mitigating or even …

This article reports on a proof of concept demonstration of a recently proposed spatial
channel network (SCN) that was conducted over an SCN testbed that comprises low-loss …

This chapter aims to provide a comprehensive picture of the impact of fiber nonlinear effects
on modern coherent wavelength division multiplexing (WDM) systems' performance. First …
