Japanese engineers broke the world record for the highest internet speed, achieving a data transfer speed of 319 Tb/s, nearly twice as fast as the previous record of 178 Tb/s, which was set less than a year ago.
This new achievement was made possible by combining existing fibre optic infrastructure with more advanced technologies. Instead of the traditional standard core, the research team used four "cores," which are glass tubes placed in the fibres that transmit data. Using a technique called wavelength division multiplexing (WDM), the signals are then separated into numerous wavelengths and broadcast at the same time.
