Japan breaks records by sending 127,500 GB per second via fiber optics • ENTER.CO

Japan has just broken a record that is difficult to measure in terms of the speed of data transfer over the Internet achieved through fiber optics. Researchers from the National Institute of Information Technology and Communications managed to send 127,500 GB per second by implementing a technique compatible with traditional infrastructure, which was capable of tripling the speed of the connection, which in 2021 alone had reached 319 terabytes per second to 3,000. kilometres.

This record differs from the previous one not only because of the amount of data sent, because on this occasion it was possible to reach, for the first time in history, a transfer speed of 1.02 petabits per second, although at a shorter distance; exactly 51.7 kilometers.

However, the milestone is important because it shows that it is only a matter of time before the current optical fiber can be optimized to such an extent that it is not necessary to replace all the cabling and reduce renovation costs.

To beat this record of transferring an impressive 1,073,741,824 Mbps, the Japanese researchers used a standard 0.125mm fiber optic cable, to which signal modulation and amplification techniques were applied, according to Computer Today. On this occasion, the scientists went from transmitting from one to four cores, from which specific data packets were sent through each of them, without mixing the signals.

The strategy proved that leaving aside the multimodal technique, the need for new hardware and the implementation of new circuits, to give prominence to the multicore cable, can optimize the transfer speed to such an extent that the bandwidth achieved would have been capable of to download ten million movies in 8K resolution in a single second: an abysmal difference that exceeds, at least three million times, the current standard Internet speed of 300 Mbps.
