China’s hollow-core fiber trial pushes 51.3 Tb/s over 128 miles without signal regeneration — milestone targets AI-era networking bottlenecks

YOFC, China Telecom, and Dekoli claim a 51.3 Tb/s hollow-core fiber field-trial record over 206.5 km, using 1.2 Tb/s-per-wavelength WDM transmission without repeaters or remote-pumped amplifiers.
