US EditionJapan Sets New Internet Speed World Record — 4 Million Times Faster than Average US Speeds
JAPAN, JUL 14 – Japanese researchers achieved 1.02 petabits per second using a 19-core optical fiber, enabling data speeds 16 million times faster than India's average, advancing future high-capacity networks.
- In June 2025, Japanese engineers at the National Institute of Information and Communications Technology achieved 1.02 petabits per second, transmitting data over 1,909 km.
- Amid surging data use from AI, VR and IoT, including Japan’s 2021 record of 319 Tbps, driven by data traffic growth, Japan has long pushed internet boundaries.
- Using MIMO processing, researchers untangled combined signals, with optical amplification relays maintaining signal strength, and a 19-core optical fiber cable serving as a '19-lane highway' for data.
- The breakthrough could download Wikipedia 10,000 times in one second, transfer over 1,500 80 GB files under a second.
- Researchers envision seamless cloud computing worldwide, with NICT plans to extend the technology across oceans, enabling global data centers to connect as if on a local network.
