Sometimes we complain about our internet connection speed at home. Yet, researchers all over the world work to increase the speed of data transfer on the net, and in Japan, they have reached crazy speeds!

In fact, a team of engineers in Japan has set, in November 2021, a new world record for fastest internet speed reaching a whooping 319 terabits per second (Tb/s).

This means, should you have the average home internet speed in the US (i.e. 42 megabits per second), you could download as many as 79750 movies (at 4 GB each) in just one second.

The new record speed, set by the National Institute of Information and Communications Technology, is two times faster than the previous one.

To establish the new speed record, the researchers used a fiber-optic infrastructure that already exists, with some specific, advanced boost. The research team…
