Japan breaks world record for fastest internet speed


Engineers in Japan established a new world record for the fastest internet speed – and it’s so fast you could almost download 80,000 films just a second.

Need of speed: the Internet Speed ​​is typically measured by the amount of data that can be transmitted between two devices in one second.

The new record is 319 terabits per second (Tb / s). It’s double previous world record for the fastest internet speed and around 7.6 million times faster than the average home internet speed in the United States (42 megabits per second).

Fiber optic cables: Different types of Internet connections transmit data over different types of hardware. Old dial-up connections, for example, relied on telephone wires, while the fastest type of Internet available today – fiber – uses fiber-optic cables.

These cables transmit data using pulses of light, which travel along thin optical fibers with glass or plastic cores.

It may not be too difficult to integrate the technology into the existing infrastructure.

To break the record for the fastest Internet speed, researchers at the Japan National Institute of Information and Communications Technology developed an experimental optical fiber with four cores, instead of just one.

They then combined their fiber with a laser that triggered pulses at different wavelengths and several signal amplification techniques. This allowed them to transmit data over a distance of over 1,800 miles at 319 Tb / s.

Perfect fit: The laser and amplifiers used to break the fastest internet speed record don’t come cheap, so don’t expect 300 Tb / s internet at home soon.

However, there is a part of the experience that could will have an impact on your life in the not-so-distant future: fiber optics.

The researchers succeeded in wrapping the four cores in a fiber the same diameter as the single-core fibers used to provide today’s fiber optic internet. This means that it may not be too difficult to integrate the technology into the existing infrastructure.

“[I]It is hoped that these fibers will be able to allow a practical high speed transmission of data in the short term, contributing to the realization of the backbone communication system necessary for the diffusion of new communication services beyond 5G ”, they write in their paper.
