Researchers at the National Institute of Information and Communications Technology in Japan have set a new world record for the world’s fastest Internet speed of 319 terabytes per second in the form of long-distance transmission over 3,001 kilometers.
The record was previously held by researchers at the University College of London at 178 Tbit / s.
The research was headed by Benjamin Puttnam and successfully completed the first S, C and L band transmission over long distances through a four-core glass fiber with a standard diameter of 0.125 mm. They showed that the use of erbium and thulium doped fiber amplifiers along with Raman amplification made this incredible feat possible.
According to the teams, they developed a transmission system with the ability to use all of the wavelength division multiplexing technology. They used various amplifier technologies to achieve a transmission demonstration data rate of 319 terabytes per second. At the same time, they were the first to produce 957 petabits per second x kilometers – a world record for glass fibers with a standard outer diameter.
