Microsoft’s Azure Fibre R&D team — working with researchers from the University of Southampton and the Lumenisity spin‑out — has published results showing a hollow‑core (air‑cored) optical fiber with record low attenuation of 0.091 dB/km at 1,550 nm, a broad low‑loss spectral window, and...

Microsoft and the University of Southampton have published what the teams describe as a watershed result in optical communications: a hollow‑core optical fiber with measured attenuation of 0.091 dB/km at 1,550 nm, a performance level that — if reproduced in production volumes and field...

In the relentless race to define the future of the internet’s infrastructure, an esoteric breakthrough has nudged the UK and Microsoft into center stage: hollow core fibre (HCF) technology. Though fibre optic cables are the backbone of today’s digital world, their essential design—glass...
