With the official adoption of the single-wavelength 50G PON standard at the International
Telecommunication Union Study Group 15 (ITU-T SG15) meeting, both industry and …

Acknowledging the predominantly hubbed traffic profile in the metro, we apply digital
subcarrier multiplexing techniques to 400Gb/s coherent pluggable optics, enabling a point …

International standardization bodies (IEEE and ITU-T) working on the evolution of
transmission technologies are still considering traditional direct detection solutions for the …

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

Recently, to cope with the ever-growing traffic volumes and network services in the Internet,
the coherent point-to-multipoint transceivers (P2MP-TRXs) enabled by digital subcarrier …

A passive optical network (PON) with low cost and high capacity has been explored and
recommended for supporting the emerged commercial mobile fronthaul, resident, and …

Passive Optical Networks (PON), able to operate at 50 Gbps per wavelength (λ), are under
development and standardization, based on intensity-modulation (IM) and direct-detection …

In this paper, we review the latest progress in the simplified digital coherent technologies
suitable for future beyond-100G optical access systems, which will be a key optical transport …
