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.
