Japan Sets A New Internet Speed Record With 319 Terabits Per Second

Don’t you sometimes wish your internet speed was a bit faster when browsing the web, streaming online content, playing multiplayer games, or participating in a video conference? Most people do, including scientists at Japan’s National Institute of Information and Communications Technology (NICT). Recently, NICT set a new internet speed record when a group of its scientists successfully transferred data at 319 Terabits per second (Tbps) over a simulated 3,001-kilometer distance.

To put the record-breaking data transfer speed into perspective, the average fixed broadband download speed worldwide currently sits around 100 Mbps, which is around 3 million (yes, million) times slower. The new record is a significant achievement even as far as internet speed records go because it’s almost double the previous world record (179 Tbps), which was achieved by British and Japanese researchers in August 2020.

Transmitting data at such an unimaginably fast speed required plenty of innovation and cutting-edge technologies. Whereas typical fiber-optic cables have just one core designed for light transmission, the cable used by the team of Japanese researchers who set the new record had four cores. The transmitted data was fired using a 552-channel comb laser at multiple wavelengths and given a boost by rare earth amplifiers.

Since the entire test took place under laboratory conditions, you shouldn’t expect your local internet service provider to follow suit in the near future by implementing similar technologies due to their cost. The most likely real-world applications of the cutting-edge system involve high-speed backbone communication.

“It is hoped that such fibers can enable practical high data-rate transmission in the near-term, contributing to the realization of the backbone communications system necessary for the spread of new communication services beyond 5G,” write NICT researchers.

Considering how much we’ve progressed since Caltech set its 186 Gbps internet speed record in 2011, we can’t help but imagine where we’ll be in another decade or two.
