Optical wideband communication systems aim at transmitting over several, if not all, of the
low-loss windows of single-mode fibre, ie the O-, E-, S-, C-, and L-band. Recently, there has …

Recently, we demonstrated a record single-mode fibre net throughput of 178.08 Tbit/s. In this
paper, we model this experiment, investigating the main limitations and challenges behind …

Multi-band optical transmission promises to extend the lifetime of currently deployed
networks. We propose a provisioning scheme tailored for multi-band systems. We show how …

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 …

Multi-band (MB) optical transmission promises to extend the lifetime of existing optical fibre
infrastructures, which usually transmit within the C-band only, with C+ L-band being also …

Multi-band optical fiber transmission is generally proposed for capacity upgrades in optical
transport networks. To comprehensively assess the potential of multi-band transmission, key …

In the past few years, the demand for high data rate services has increased dramatically.
The congestion in the radio frequency (RF) spectrum (3 kHz~ 300 GHz) is expected to limit …

Telecommunication networks are becoming the central linking institution of the Fourth
Industrial Revolution. To cope with the associated capacity and connectivity challenges …

In this work we detail the strategies adopted in the European research project IDEALIST to
overcome the predicted data plane capacity crunch in optical networks. In order for core and …
