GoKawiilChinese researchers set 3.2 Pb/s real-time fiber-optic transmission record
A team from China's National Key Laboratory of Optical Communication Technology, along with Pengcheng Laboratory, CICT, and Fiberhome Fujikura Fiber Optic Technology, achieved a real-time data transfer speed of 3.2 petabits per second over 24-core optical fiber cable. This surpasses their own previous record of 2.5 Pb/s set earlier this year, marking close to a 30% improvement, and was achieved using spatial division multiplexing combined with S+C+L multi-band transmission technology on commercially compliant hardware.
GoKawiil's interpretation of the reporting above, not reported fact.
Because the test used commercially viable hardware rather than purely experimental lab setups, the result suggests this speed could eventually be deployed in real-world networks rather than remaining a theoretical benchmark. If scaled, the technology could support gigabit broadband for millions of households simultaneously, though actual rollout would depend on infrastructure investment and further engineering to address challenges like crosstalk interference across transmission bands.
- Chinese researchers hit 3.2 Pb/s real-time transfer speed over 24-core optical fiber, up from 2.5 Pb/s earlier this year.
- The achievement relies on spatial division multiplexing and S+C+L multi-band transmission using commercially compliant hardware.
- Pure lab experiments have reached even higher speeds of up to 5.29 Pb/s, but this result emphasizes real-world deployability.
