3.2 Petabits per second real-time optical fiber transfer speed world record claimed by Chinese team

A Chinese research team has set a new record for the fastest real-time optical fiber data transfer speed, reaching 3.2 petabits per second, according to a report by the Hubei Province government website. The achievement, a result of collaboration between the National Key Laboratory of Optical Communication Technology, China Information and Communication Technologies Group, Pengcheng Laboratory, and Fiberhome Fujikura Fiber Optic Technology Co., Ltd., represents a significant leap forward in optical communication technology.

The team utilized spatial division multiplexing and S+C+L multi-band transmission technology to achieve this remarkable speed, which is equivalent to downloading "more than 20,000 4K movies" per second or being 3.2 million times faster than a standard one-gigabit internet connection. This breakthrough could potentially enable "3.2 million households to enjoy gigabit broadband simultaneously."

The researchers faced technical hurdles such as crosstalk interference and the need to accommodate varying specifications of the S+C+L transmission bands. However, they successfully employed commercially available hardware architectures to demonstrate the practicality of this record-breaking speed, suggesting that it could become a viable deployment option in the near future.

While other research teams have achieved even higher speeds in laboratory settings, reaching up to 5.29 petabits per second using advanced signal processing and specialized equipment, the 3.2 petabits per second record achieved by the Chinese team demonstrates a significant milestone in real-world optical fiber communication technology development.
