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

A Chinese team has claimed a new world record for real-time transfer speeds across 24-core optical fiber cable. The collaboration between the National Key Laboratory of Optical Communication Technology, and Network of China Information and Communication Technologies Group, Pengcheng Laboratory, and Fiberhome Fujikura Fiber Optic Technology Co., Ltd. hit speeds fast enough to download “more than 20,000 4K movies” in one second, reports the Chinese government website for Hubei Province.

  • Photonics and high-speed data movement is the next big AI bottleneck
  • Co-Packaged Optics (CPO) foundry roadmaps
  • Inside optical and the battle for scale – how the AI industry is racing to integrate photonic interconnects
  • How optical interconnects and silicon photonics emerged as AI's next hot commodity
  • Near-packaged optics (NPO) gains ground as the industry hedges against CPO's growing pains

We note that this new 3.2 Pb/s real-time optical transfer speed world record comfortably eclipses the 2.5 Pb/s record set by the same teams earlier this year. The improvement represents an almost 30% performance uplift within a year.

According to the source, these speeds could mean, if and when they are successfully rolled out, “3.2 million households simultaneously enjoying gigabit broadband.” Or you could say this speed is roughly 3.2 million times faster than a typical one-gigabit internet connection. Both are probably more useful and practical comparisons than knowing that one person would be able to download 20,000 4K movies in a single second.

2 Pb/s test proved the success of the spatial division multiplexing and S+C+L multi-band transmission technology used by the team.
