From PC Mag: In a possible glimpse at future internet speeds, scientists in Japan recently powered a 402,000 Gbps connection using commercially available optical fiber.
The research comes from Japan’s National Institute of Information and Communications Technology (NICT), which has partnered with other labs to use existing optical fiber tech to deliver huge speed enhancements.
In March, one of NICT’s partners on the project, Aston University in the UK, beamed internet speed at 301,000 Gbps over a single, standard optical fiber. NICT has since followed up with another test, hitting 402,000.
The feat was achieved by harnessing additional wavelength bands—essentially colors—within the optical fibers to increase the data transmission rate. Specifically, NICT scientists tapped the O-, E-, and S-bands to amplify the data when the C- and L-bands are typically used for long-haul transmission over fiber networks.
