A paradigm shift in optical communication networks is proposed, with the introduction of a
new ecosystem of devices and components with the capability of transforming current point …

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 …

The massive deployment of 5G and beyond will require high capacity and low latency
connectivity services, so network operators will have either to overprovision capacity in their …

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

Point-to-multipoint (P2MP) coherent optics using digital subcarrier multiplexing have
recently been proposed as a promising new technology to reduce the cost and complexity of …

In aggregation networks, the traffic patterns resemble hub-and-spoke characteristics, with a
few hub nodes connecting several leaf nodes to the outside of the networks. The use of …

This paper describes the problematic filter narrowing effect in the context of next-generation
elastic optical networks. First, three possible scenarios are introduced: the transition from an …

Point-to-multipoint (P2MP) optical coherent transceivers, which take advantage of digital
subcarrier multiplexing, can greatly simplify design, planning and operations in next …

We propose and demonstrate a new low-complexity hardware architecture and digital signal
processing (DSP) implementation for coherent reception of Nyquist frequency division …

Next-generation elastic optical interfaces will support a wide range of line rates and
modulation formats. Such transmission schemes enable doubling of the channel capacity at …
