RIO — Engineers at a technology center in Japan managed to break the record for the highest fiber-optic internet speed by registering 319 terabits per second. To get an idea of how fast this is, the download of the video game “Call of Duty: Modern Warfare”, one of the heaviest games, with about 200 gigabytes in size, could be done in less than a second at this rate obtained by researchers.

Led by Benjamin J. Puttnam, they built a transmission system that works with different wavelengths over a distance of 3,001 kilometers. It was also verified that such speed was 2.7 times higher than the last demonstration performed involving SDM fibers with standard external diameter.
According to the authors of the demonstration, this was the first transmission of S, C and L bands over long distances on a four-core optical fiber with a standard outer diameter (0.125 millimeters).

“In addition to the C and L bands, normally used for long-distance transmission and high data rate, we use the S-band transmission bandwidth, which has not yet been used beyond the single transmission interval.”
