Existing Fiber Tech Achieves 402,000 Gbps Internet Speed: Study

The National Institute of Information and Communications Technology (NICT) in Japan, in partnership with various global laboratories, is utilizing existing optical fiber technology to deliver significant enhancements in internet speed. In a recent test conducted by the NICT, an impressive 402,000 Gbps connection was achieved using commercially available optical fiber.

This groundbreaking research project has seen several milestones already. Earlier this year, in March, Aston University from the UK, one of NICT's collaborators on this initiative, successfully transmitted data at a staggering rate of 301,000 Gbps over a single standard optical fiber. Not long after that feat, NICT outdid it by reaching speeds up to 402,000 GB/s.

These remarkable speeds were made possible through the innovative use of additional wavelength bands within the optical fibers. Typically, for long-haul transmission over fiber networks, only C- and L-bands are used, but this time around, scientists at NICT utilized O-, E-, and S-bands as well to amplify data transmission rates significantly.

By doing so, they were able to enable "a total of 1,505 wavelength channels" within the given optic bandwidth. Each channel delivered a data rate exceeding 250 GB/s, which, when combined, resulted in theoretical internet speeds as high as an unprecedented 402 GB/s over a distance of about fifty kilometers via what is referred to as "water absorption peak suppressed optical fiber."

To effectively tap into these additional wavelength bands, it required developing six different types of "doped fiber-optical amplifiers." These special amplifiers utilize small amounts of rare earth ions like erbium, thulium, or bismuth ions, which have proven instrumental not just for increasing range but also enabling simultaneous amplification across multiple wavelength channels, according to statements issued by NICT.

Despite achieving such breakthroughs, there is no official word yet on when we can expect commercialization of this advanced technology. However, it should be noted that other industry leaders, including Nokia Bell Labs and Hong Kong's Amonics, have been working in partnership with NICT on the development of this optical fiber technology.

NICT, meanwhile, continues to remain focused on furthering their research to extend transmission range for such wideband, ultra-high-capacity systems as well as improving their compatibility for deployment over field fibers.

These advancements are a promising indicator of what lies ahead in terms of internet speed capabilities. As we continue to see an exponential increase in global data traffic, the need for faster and more efficient data transmission technologies becomes paramount. The work being done by institutions like NICT is therefore not just commendable but also absolutely critical for catering to our ever-growing digital needs.
