Gas Line Absorption Mitigation in Hollow-Core Fibre using Spectral Pre-Equalisation
arXiv:2602.09668 · doi:10.1364/OFC.2026.Th2A.50
Abstract
We study the impact of CO 2 absorption on hollow-core fibre transmission. Using spectral pre-equalisation, we digitally post-compensate gas-line absorption and show a 5.5 dB reduction in Q-factor penalty, outperforming a 383-tap equaliser by 1.3 dB.
