Wavelength-division multiplexing (WDM) has historically enabled the increase in the
capacity of optical systems by progressively populating the existing optical bandwidth of …

C+ L open line systems represent a cost-effective way to scale backbone network capacity.
In this article, we review challenges and opportunities for C+ L line systems stemming from …

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 …

The various topologies, traffic patterns and cost targets of optical networks have prevented
the deployment of end-to-end solutions across multi-domains, and the optimization of the …

We investigate optical transmission of an ultra-wideband signal in a standard single mode
fiber. Using a near continuous optical bandwidth exceeding 157 nm across the S-, C-and L …

Opening new wavelength bands is the most economic step for further increasing the
capacity of optical transmission links. Characteristics of different amplifier technologies for …

The maximum data throughput in a single mode optical fibre is a function of both the signal
bandwidth and the wavelength-dependent signal-to-noise ratio (SNR). In this paper, we …
