Japan’s new web velocity report makes at the...

Over the previous 20 years, internet speeds have vastly improved because of advances in fiber expertise. Whereas gigabit web is turning into more common within the US, it nonetheless lags behind the speeds not too long ago achieved by researchers in Japan.

In accordance with the Nationwide Institute of Info and Communications Know-how (NICT) in Japan, it has set a brand new world report for web velocity, reaching 1.02 petabits per second over a distance of 1,123 miles. That equals about 127,500 GB/s, and roughly the space between Chicago and Dallas. With that velocity, you can obtain Netflix’s total streaming library in only one second (through CNET). You’d additionally by no means have a problem downloading a 100GB online game ever once more.

Within the US, web velocity is often measured in megabits per second (Mbps). When you convert Japan’s achievement, it equals roughly 1,020,000,000 Mbps. In accordance with Speedtest, the typical mounted broadband web velocity within the US is round 288 Mbps. So, the velocity researchers in Japan have simply reached is greater than 3 million occasions sooner.

How did NICT researchers obtain this?

They used a 19-core optical fiber cable

Japan’s NICT achieved its new web velocity report by growing an optical fiber with 19 cores, built-in right into a cable measuring simply 0.125mm in diameter. This measurement is normal for fiber optic cables used globally, indicating potential for widespread adoption as a result of its compatibility with current community infrastructure, like undersea cables.

“The analysis of ultra-high-capacity transmission utilizing coupled 19-core optical fibers and superior optical amplification has drastically superior the event of expertise for the conclusion of high-capacity, long-distance optical communication infrastructure sooner or later,” the NICT report states.

This is not the primary time the NICT has damaged a report both. Final yr, it shattered the web velocity report with a velocity of fifty,250 GB/s. Now in 2025, it has damaged its report by over double.

With the worldwide demand for greater web bandwidth rising — particularly for cloud storage, AI, and high-quality streaming — the NICT’s breakthrough marks a significant step in addressing the growing want for extra bandwidth. In accordance with Nielsen’s Law, world bandwidth calls for have elevated by 50 % yearly since 1983, indicating that at some point, 1.02 petabits per second could also be wanted.
