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

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

The utilization of distance-adaptive coherent optical transceivers in combination with a
flexible finer-grained Wavelength Division Multiplexing (WDM) grid has been proposed in …

In this paper, we investigate a novel problem for dimensioning optical networks with digital
subcarrier-based point-to-multipoint (P2MP) coherent transceivers, which we refer to as tree …

Nowadays, the booming of emerging network services have shifted the major traffic pattern
in metro-aggregation networks from point-to-point (P2P) to hub-and-spoke (H&S). Hence, it …

Continued cost-and power-efficient capacity scaling in optical networks is imperative to keep
pace with ever-increasing traffic demands. In this paper, we investigate multi-wavelength …

Given the introduction of coherent 100G systems has provided enough fiber capacity to meet
data traffic growth in the near term, enhancing network efficiency will be service providers' …

We propose a new metric called hubbedness to describe traffic flow in modern optical
networks. We compare theoretical savings of point-to-multipoint vs point-to-point …

This paper proposes an integer linear programming framework to optimize the multi-period
planning of metro-aggregation networks exploiting point-to-multipoint coherent pluggable …
