In this paper, we discuss building blocks that enable the exploitation of optical capacities
beyond 100 Gb/s. Optical networks will benefit from more flexibility and agility in their …

The performance of high-speed intensity modulation direct detection (IM-DD) transmissions
is severely degraded by the linear inter-symbol interference (ISI), due to both bandwidth …

Network function virtualization is an emerging network resource utilization approach which
decouples network functions from proprietary hardware and enables adaptive services to …

The escalating demand for greater transmission capacities in the forthcoming 6? G
communication landscapes necessitates the investigation of upper segments of the …

This tutorial paper reviews advanced modulation techniques that have been proposed in the
literature for the implementation of flexible (or reconfigurable) transceivers, which are …

This paper presents a systematic review of several digital signal processing (DSP)-enabled
technologies recently proposed and demonstrated for high spectral efficiency (SE) 400 Gb/s …

We propose a RF-pilot aided modulation format identification (MFI) technique to enable a
hitless flexible coherent transceiver with fast format switching. For the MFI, modulation format …
