Record 202.3 Tb/s Transmission over Field-Deployed Fibre using 15.6 THz S+C+L-Bands

TL;DR

This paper demonstrates a record ultra-wideband metropolitan fibre transmission achieving over 200 Tb/s, using experimental optimization and pre-tilt techniques to overcome nonlinear effects across a 15.6 THz bandwidth.

Contribution

It presents the first experimental demonstration of ultra-wideband fibre transmission exceeding 200 Tb/s over field-deployed infrastructure.

Findings

Achieved 202.3 Tb/s GMI transmission

Optimized 15.6 THz bandwidth with 5 dB pre-tilt

Overcame ISRS effects in field deployment

Abstract

Ultra-wideband, field-deployed metropolitan fibre transmission is experimentally demonstrated, measuring a record 202.3 Tb/s GMI and 189.5 Tb/s after decoding with 20.9 dBm launch power and lumped amplification only. An experimentally-optimised 5 dB pre-tilt over the 15.6 THz optical bandwidth was applied to overcome ISRS.
