Chinese companies YOFC and China Telecom, along with Dekoli, have set a new world record for unrepeatered hollow-core fiber transmission, achieving 51.3 Tb/s over approximately 128 miles. This trial utilized 1.2 Tb/s per wavelength wavelength-division multiplexing without signal regeneration, relying only on standard erbium-doped fiber amplifiers. The advancement in hollow-core fiber technology, which guides light through an air-filled channel, promises lower latency and higher speeds, addressing critical networking bottlenecks anticipated in the AI era.
