Field trial of SDN-controlled probabilistic constellation shaping supporting multiple rates over a coupled-core multi-core fiber

A SDN controller configures probabilistic constellation shaping through NETCONF optimizing spectral efficiency according to the path length or degradations due to soft failure. The integrated data and control planes are demonstrated with multiple rates (800-850-900-950-1000Gb/s) in a field trial employing multi-core fiber with 4-coupled cores. (C) 2022 The Author(s)

Automated summary

This paper presents how a SDN controller configures probabilistic constellation shaping via NETCONF to optimize spectral efficiency based on path length or degradations caused by soft failure. The integrated data and control planes are demonstrated in a field trial using multi-core fiber with 4-coupled cores and multiple rates (800-850-900-950-1000Gb/s).
