A Chinese research team has set a new world record for real-time data transfer, achieving speeds of 3.2 Petabits per second over a 24-core optical fiber cable. This milestone was reached through a collaboration between the National Key Laboratory of Optical Communication Technology and Network, Pengcheng Laboratory, and Fiberhome Fujikura.
The test utilized and S+C+L multi-band transmission technologies. Researchers successfully addressed crosstalk interference and varying specification requirements across bands using commercially compliant hardware. This 3.2 Pbps rate is approximately 3.2 million times faster than a standard one-gigabit connection.
This achievement marks a 30% improvement over the team's 2026 record of 2.5 Pbps. While academic lab milestones have reached 5.29 Pbps, this real-time result demonstrates massive capacity, equivalent to downloading 20,000 4K movies in a single second, signaling a significant leap forward for high-capacity optical networking infrastructure.
