Japan has reached almost twice the world record speed of the Internet. A team of engineers from the country’s National Institute of Information and Communication Technology (NICT) reached 319 terabits per second. At the same time, they have been able to maintain this speed from a distance of 1,856 miles.
In this case, for the first time, the team of engineers has experimentally applied the transmission technology of ‘S’, ‘C’ and ‘L’ bands together. Their technology has worked well with existing four-core optical fiber equipment across the fiber amplifier.
Earlier, in August 2020, British and Japanese researchers recorded a speed of 178 terabits per second.
This time NICT achieved this feat by upgrading almost every stage of the pipeline. The fiber optic line had four cores instead of one, and the researchers cast a 552-channel comb laser over multiple wavelengths with the help of a rare earth amplifier. Although the experiment was strictly confined to the lab, the team used coil fibers to transmit data over a mock 1,864 miles without losing signal quality or speed.
