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.
The accelerating demands of AI and data-intensive applications are pushing the limits of current fiber optic technologies, necessitating innovations in high-bandwidth, low-latency data transmission.
This breakthrough addresses critical networking bottlenecks for the AI era, potentially enabling more distributed and efficient AI infrastructure by negating the need for frequent signal regeneration.
Networking capabilities can now achieve significantly higher data rates over longer distances without active repeaters, reducing infrastructure complexity, cost, and power consumption for high-bandwidth applications.
