New internet speed record broken in Japan with 1.02 petabits per second

Even though the data transfer rates offered to users over fiber optic cables are quite limited today, new records continue to be broken by researchers. Japanese engineers, who set a record with a transfer rate of 319 terabits/sec last year, have now set the bar to an unattainable level.

A speed of 1.02 petabits per second was reached

Reportedly, a research team at Japan’s National Institute of Information and Communications Technology has tested a technique called wavelength division multiplexing (WDM) at a distance of 51.7 kilometers. Using the technique, it reached a data transfer rate of 1.02 petabits per second.

The researchers, who managed to increase the bandwidth of the line up to 20 THz with the WDM technique, which provides the new value, states that the mentioned speeds are equivalent to 127,500 GB file transfer per second or 10 million 8K videos per second.

In addition, using a quad-core cable instead of the single fiber optic core cable used today, the researchers stated that data is transmitted in only one mode per core. Thus, we can say that the new technology can be easily adapted to existing lines.
