082026-11China completes 1,000-km bidirectional real-time hollow-core fiber transmission testChina has completed the world's first 1,000-km bidirectional real-time hollow-core fiber transmission test, achieving simultaneous 64 Tb/s transmission in each direction over a 1,007.48-km line with a one-way latency of 3.43 milliseconds. Hollow-core fiber offers double the transmission capacity and 30% lower latency than solid-core fiber, laying a key technical foundation for computing-power networks.IT之家
