Researchers at Japan’s National Institute of Information and Communications Technology (NICT) set a new record for internet speed: 319 Terabits per second (Tb / s), in an experiment carried out in the faculty’s laboratories. As a comparison, the latest mark was 178 Tb/s achieved by scientists at University College London (UCL) in August 2020.
While exciting, speed is a long way from reaching our homes and smartphones. Cell phone makers and phone operators are currently working to implement the 5G internet, which has a promised speed of up to 500 Mb/s without relying on wires. The Japanese brand is almost 640,000 times larger, but dependent on threads.

The experiment was carried out by the NICT using a special fiber optic cable with four cores in the space of just one. According to the website Vice, who announced the news, this is important for rapid adoption taking advantage of current wiring structures and facilities.
In the test, the scientists simulated sending a data packet over a distance of 3,000 km and managed to do so without losing speed. For this analysis, they used a 552-channel laser comb, emitting waves of varying lengths, which were driven by amplifiers made from rare minerals.
The expenditure on material to achieve this speed is enormous, which could make the use of technology unfeasible on a daily basis in the short term. However, maybe the average user doesn’t even need that much at the moment, since streaming services like Netflix, to cite an example, require a connection of only 25 Mb/s. Applications involving games, telemedicine and more robust transmissions may require faster connections.
In fact, researchers thought of this technique to carry large amounts of information as far away as possible in a short amount of time, without signal degradation, which should find use on an industrial scale.
