Optical fiber allows Internet speed to be continuously tested,Motherboard Quoting the latest information from the National Research and Development Corporation of Japan (NICT)Test Results, They succeeded in achieving a data transmission speed of 319Tbps on the Internet. The last record was actually the 179Tbps speed jointly set by Japanese and British researchers in August 2020. As a result, it was refreshed again today with a doubled result.
This time, NICT has completely upgraded the entire optical fiber communication specifications, including the optical fiber that has been multiplied from single-core to four-core. At the same time, with the assistance of rare earth amplifiers, it is radiated to multiple different wavebands through 522-channel comb lasers. Although the experiment was done in the laboratory, for the sake of rigor, the researcher also wrapped the optical fiber to simulate a distance of about 3,000 kilometers (1,864 miles) to ensure that the signal did not lose any content or speed.
Just like other advanced technologies, such high-speed optical fiber transmission specifications will not be practically applied in the near future, especially the optical fiber lines must be upgraded to four-core lines, which will inevitably bring a certain upgrade cost, and it is also in the backbone. Infrastructure such as transmission will use this speed. However, NICT said that this next-generation optical fiber transmission technology will be able to provide assistance for technologies beyond 5G (like 6G?), so it can be regarded as laying the foundation for the future.
