There is a new world record for internet speed that is 3.5 million times faster than the US and can download the entire Netflix library in just one second.

It turns out that Japan remains ahead of the game when it comes to the advancement of technology and the country’s internet speed is no different.

While it might take you hours to download certain games or a few minutes to get a season of your favorite show downloaded from Netflix, in Japan, you could have the streaming service’s entire catalogue saved in just the blink of an eye.

This is all down to the fact that the Japanese internet has speeds of 1.02 petabits, which means it has the record for being the fastest internet across the globe.

According to a report by the National Institute of Information and Communications Technology (NICT), the US’s internet has an average speed of around 242 Mbps, meaning that Japan’s is quicker by 3.5 million times.

The internet in Japan was created when the Photonic Network Laboratory team at Japan’s NICT, joined forces with Sumitomo Electric and European Partners, to make the world’s fastest network.

Achieving this, they were able to make an internet which sends data over 1,808 km per second using a special fiber optic cable with 19 cores.

The optic fiber cable is the same size as what’s currently used in the industry, measuring at 0.125 mm thick.

However, the total data sent across the large distance was 1.86 exabits per second times kilometres, which is the highest ever achieved in history.

Sumitomo Electric designed the optical fiber cable, and NICT built the transmission system, using transmitters, receivers and 19 looping circuits, 86.1 km long.

The signals then passed through the loops 21 times to carry 180 data streams to its destination.

If talking about Netflix downloads isn’t enough to convince you of how fast it really is, it’s estimated to be able to download the entire English Wikipedia 10,000 times in just one second, which would take about100 GB of space, as per Gagadget.

As for downloading 8k videos, that also takes just a second, and you could also download Steam’s entire game library which is around 1.2 petabytes within 10 seconds.

In terms of music, you could download 1,27,500 years’ worth of it in a blink of an eye, which would give you one hell of a playlist that you’d never be able to complete.

So, can we get this type of network in the US? Unfortunately, it’s unlikely to happen anytime soon as the US isn’t on the same level as Japan in regard to innovating its internet connection.
