Microsoft’s engineering teams have taken a familiar security posture—the Zero Trust mindset—and applied it to the physical fabric of their campuses, producing a dual‑domain optical architecture that pairs a production ROADM transport with a physically independent MUX‑based backup to deliver what...

Researchers at the University of Southampton, working with Microsoft Azure Fibre engineers, have demonstrated a hollow‑core optical fiber that sets a new laboratory record for low attenuation and promises markedly lower latency and higher spectral capacity than conventional silica single‑mode...

Microsoft’s move to outsource hollow‑core fiber (HCF) production to established glass and fiber manufacturers marks a key inflection point for a technology that has long promised dramatic gains in latency, bandwidth and energy efficiency for cloud and AI workloads. Over the last week Microsoft...

The hollowing-out of fiber optics just passed an important milestone: a research team tied to Microsoft and the University of Southampton has reported a hollow‑core optical fiber design that both lowers signal loss below the long‑standing practical floor for silica fiber and propagates light...

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...
