Researchers in Japan set a new world record for internet speed of 319 terabytes per second.
According to the Russian “Sputnik” agency, a team of researchers at the “Japanese National Institute of Information and Communications Technology” used advanced optical fiber technology with four-core optical fibers with a standard outer diameter of 0.125 mm to conduct a speed test.
This broke the previous record of 178 terabytes per second set by engineers in Japan and Britain a year ago.
To achieve the record speed, the researchers built an experimental recycled transmission loop by combining two types of rare earth fiber amplifiers.
The combination of erbium-thorium-fiber amplifiers and distributed Raman amplification allowed long-distance transmission of more than 3,001 kilometers.
According to Hindustan Time, the Japanese institute stressed that it is important to show how the new fibers can meet the apparent "explosive" demand from new data services.
The research institute further noted that the result of the latest Internet speed test will help realize new communication systems, which can support "bandwidth-hungry services", adding that they will continue to explore ways to increase the "low" transmission capacity.
