423.7 + 426.5 Tb/s GMI Bi-Directional HCF Transmission
arXiv:2605.04924
Abstract
We demonstrate OESCL-band same-wavelength bi-directional transmission over 60 km HCF with 42.5 THz bandwidth, achieving GMIs comparable with the highest unidirectional SMF data-rates in both directions, with an aggregate of 423.7 + 426.5 Tb/s.
