China hits 51.3 Tb/s over 128 miles in hollow-core fiber trial

By Meridian48 News Desk · Summarised from Tom's Hardware ·

YOFC, China Telecom, and Dekoli achieved a 51.3 Tb/s data rate over 206.5 km of hollow-core fiber using 1.2 Tb/s-per-wavelength WDM without signal regeneration. The field trial aims to address AI-era networking bottlenecks by enabling higher bandwidth over longer distances. This record demonstrates the potential of hollow-core fiber for future high-capacity optical networks.

Meridian48 take
The trial is impressive but remains a lab-field milestone; commercial viability and large-scale deployment still face significant hurdles.
