The fastest internet speed was recorded in Japan, with a speed of more than 300 terabits per second (Tbps), after beating last year’s 178 Tbps.

A group of Japanese engineers developed 319 Tbps internet speed that was set on a fiber cable that covered over 3,000 kilometers, according to a paper presented at the International Conference on Optical Fiber Communications, the largest global conference, and exhibition for optical communications and networking professionals.

Japan’s National Institute of Information and Communications Technology (NIICT) developed the existing optical fiber model and operated it with minimal effort.

The group of researchers, led by Benjamin J. Puttnam, designed the fastest internet system that makes full use of wavelength division multiplexing technology by combining different amplifier technologies.

It is almost double the previously recorded internet speed of 178Tbps last year, which is capable of downloading all Netflix content in under a second.

This new 4-core optical fiber innovation can be connected with existing equipment and showing compatibility in enabling practical high data-rate transmission in the near future.

Comparatively, the fastest internet speed among regular users can reach up to 10 gigabits per second (Gbps), and National Aeronautics and Space Administration’s (NASA’s) 400Gbps.

NICCT hopes to continue developing more long-distance transmission systems, particularly trans-oceanic distances, and explore further how to increase transmission capacity.
