Japan Smashes Global Internet Speed Record with 1.02 Pbps Breakthrough
Share
Japanese researchers have achieved a record‑breaking internet speed of 1.02 petabits per second (Pbps)—equivalent to a million gigabits per second. This astonishing performance is more than three million times faster than the average U.S. connection and about 16 million times faster than average internet speeds in India (~63.55 Mbps).
What makes this even more impressive is that it was achieved using a specially engineered 19‑core optical fiber cable—each core only 0.125 mm thick, the same diameter as standard fiber already in use. The test involved sending data through looping circuits across a total distance of 1,808 kilometres, sustaining the speed across that entire span.
Thanks to this breakthrough:
-
You could download the entire Netflix content library in under one second.
-
Or transfer the entire English Wikipedia roughly 10,000 times in just one second.
Although this achievement was made in a laboratory setting, it demonstrates that ultra‑high‑speed, long‑distance data transmission is possible using today’s infrastructure. The development has major implications for future technologies like 6G networks, global AI data centers, and ultra‑low latency cloud computing.
Real‑world consumer access to such speeds isn’t on the horizon yet, but this breakthrough shows a clear path forward for future internet backbones, submarine cables, and national broadband infrastructure. Japan’s success underscores its leadership in cutting‑edge communication technology on the global stage.
