Japan’s new web velocity document makes in the present day’s broadband look historic

Over the previous 20 years, internet speeds have vastly improved due to advances in fiber know-how. Whereas gigabit web is changing into more common within the US, it nonetheless lags behind the speeds just lately achieved by researchers in Japan.

In response to the Nationwide Institute of Info and Communications Know-how (NICT) in Japan, it has set a brand new world document 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 might obtain Netflix’s complete streaming library in only one second (through CNET). You’d additionally by no means have a difficulty downloading a 100GB online game ever once more.

Within the US, web velocity is normally measured in megabits per second (Mbps). Should you convert Japan’s achievement, it equals roughly 1,020,000,000 Mbps. In response to 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 instances quicker.

How did NICT researchers obtain this?

They used a 19-core optical fiber cable

Japan’s NICT achieved its new web velocity document by creating an optical fiber with 19 cores, built-in right into a cable measuring simply 0.125mm in diameter. This measurement is customary for fiber optic cables used globally, indicating potential for widespread adoption resulting from its compatibility with present community infrastructure, like undersea cables.

“The analysis of ultra-high-capacity transmission utilizing coupled 19-core optical fibers and superior optical amplification has enormously superior the event of know-how for the belief 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 document both. Final yr, it shattered the web velocity document with a velocity of fifty,250 GB/s. Now in 2025, it has damaged its document by over double.

With the worldwide demand for increased web bandwidth rising — particularly for cloud storage, AI, and high-quality streaming — the NICT’s breakthrough marks an important step in addressing the rising want for extra bandwidth. In response to Nielsen’s Law, international bandwidth calls for have elevated by 50 p.c yearly since 1983, indicating that in the future, 1.02 petabits per second could also be wanted.
