About this tag
Optical communications at WindowsForum.com covers Microsoft's investments in next-generation fiber optic technologies, particularly hollow-core fiber (HCF) and dual-domain optical architectures. Discussions focus on Microsoft's partnerships with Corning and Heraeus to scale hollow-core fiber production, as well as research breakthroughs from Microsoft and the University of Southampton achieving record-low attenuation of 0.091 dB/km and 45% latency reduction in double-nested antiresonant nodeless fiber (DNANF). Topics also include Microsoft's Zero Trust Optical BCDR network design for campus resilience, which applies security principles to physical optical transport. These threads explore how advanced optical communications can improve data center interconnects, long-haul transport, and cloud infrastructure performance.

    Zero Trust Optical BCDR: Microsoft's Dual-Domain Campus Network for Resilience

    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...

    Microsoft Scales Hollow Core Fiber with Corning and Heraeus Partnerships

    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...

    Hollow-Core Fiber Breakthrough: 0.091 dB/km Attenuation and 45% Latency Gain

    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...
