Scientists at the National Institute of Information and Communication Technologies of Japan (NICT) have achieved a maximum data transfer speed that pulverizes any previous record, in fact almost double the previous one Internet speed record which is now 319 Tbit / s than the previous one was 179 Tbps.
This high speed was made possible through the use of technologies such as quad core fiber optics.
Almost a year ago, in August 2020, a joint team of British and Japanese researchers reached the already dizzying speed of 179 Tbit / s, which has now been significantly exceeded as the NICT researchers tried to improve all technical parameters in all environments. These are speeds that multiply many times over even the most optimistic ones that can be enjoyed today, and probably even exceed the parameters that could be measured by the various apps that are out there to measure internet connection speed from cell phones.
At the beginning is the fGlass fiber (cooled) had four cores instead of just one, and the pulse of light that carried the information was a laser that combined 552 beams of different wavelengths and was further amplified through the use of rare earths. The test carried out in the laboratory has sending the data to a distance of 3,000 km without loss Signal or speed.
In terms of the practical application of the means used in this test, cooling the fiber optic cable itself would be the most complicated (because it is extremely expensive), although quad-core cables have some presence in the communication infrastructure, therefore everything seems to suggest that the first Locations are in facilities that are limited to research centers and business complexes.
Due to the properties that are compatible with the current equipment in existing lines, the Quad core fiber it could be an important advance in the medium term that would enable improvements that would soon reach the population.
One of the greatest advantages of using this type of technology would be to provide telecommunications networks with greater capacity to support multiple broadband connections and carry a large amount of information without breaking down from saturation.
