Researchers in China achieve record optical fiber transmission speeds

Researchers in China have set a world record in optical fiber transmission by achieving real-time, two-way speeds of 64 terabits per second over a 1,007-kilometer link of hollow-core fiber. The technology cuts signal travel time by about 30 percent compared to conventional glass fiber by routing light through the fiber’s hollow center. This breakthrough offers significant potential for improving latency and bandwidth between AI data centers hundreds of kilometers apart. Open article →
