Japanese scientists again managed to surprise the world - they broke the existing record for a data transfer speed of 178 Tbit / s. Specialists from the National Institute of Information and Communication Technologies managed to reach the 319 Tbit / sec mark.
To achieve this, the scientists used a system with wavelength division multiplexing technology. A 0.125 mm fiber optic cable with a total length of ~ 3,001 km was used. Despite the truly impressive speed, now it is scientific research that is far from commercial use. It is difficult to imagine the financial costs required to replace fiber around the world.
