China tests 1,000km fiber

China has completed a data-transmission test over 1,007.48 kilometers of hollow-core optical fiber, achieving 64 terabits per second in each direction with simultaneous two-way transmission. The signal took 3.43 milliseconds to travel 1,000 kilometers one way. Compared with the best solid-core fibers, the technology doubles transmission capacity and extends transmission distance by 60%. The test confirmed that these fibers can carry data over long distances with high capacity and low latency, supporting AI data-center networks.
