Microsoft acquired UK-based HCF manufacturer Lumenisity Limited back in 2022, and in the same year, launched a HCF fabrication facility in the UK to expand production and drive innovation. It claims that its HCF, which is based on the proprietary Double Nested Antiresonant Nodeless Fiber (DNANF) design, delivers up to 47 percent faster data transmission and approximately 33 percent lower latency compared to conventional Single Mode Fiber (SMF). Our collaborations with Corning and Heraeus establish a resilient, global HCF supply chain so Azure can deliver a standardized, world-class customer experience with ultra-low latency and high reliability for modern AI and cloud workloads," said Jamie Gaudette, partner cloud network engineering manager at Microsoft.
