Record-Low-Loss Hollow-Core Fiber Achieves 45% Faster Data Transmission

Researchers from the University of Southampton and Microsoft have developed a novel hollow-core fiber (HCF) with a record-low attenuation of 0.091 dB/km at 1550 nm, significantly outperforming traditional silica fibers. This breakthrough, achieved through advanced modeling to minimize loss mechanisms, enables 45% faster transmission speeds and opens the door for longer, unamplified spans in optical communication networks.
