hollow-core fiber

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’s move into hollow‑core optical fiber signals a potential inflection point for high‑speed networking: lab and limited field results show an air‑core design with measured attenuation as low as 0.091 dB/km at 1,550 nm, a substantially lower loss than the practical floor of modern silica...

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...
