The fastest internet speed record surpassed previous records by researchers at Japan’s National Institute of Information and Communications Technology (NICT). Japan has the fastest internet speed as of now. They achieved a staggering 319 terabits per second. Engineers from Japan broke the previous record of 178 Tb/s a year ago.
In a lab, advanced fiber-optic technology was in use to conduct the speed test. Many fiber optics have one core and a lot of cladding, or coating to safeguard the data within. The NICT system employed an experimental strand of fiber optic cable with four cores contained in a cable that was about the same size as a regular fiber optic line.
“The 4-core [multi-core fibers] with standard cladding diameter is attractive for early adoption of [space division multiplexing] fibers in high-throughput, long-distance links, since it is compatible with conventional cable infrastructure and expected to have mechanical reliability comparable to single-mode fibers,” NICT stated in a paper about the experiment.
That’s remarkable. But there’s still a lot of work remaining
NICT looped the data via coiled fiber optic bits. It is to mimic a transmission distance of 3,001 km (1,864 miles) without signal or speed loss. That’s remarkable. But there’s still a lot of work remaining and getting to this pace was difficult.
The researchers employed a 552-channel comb laser that fired at different wavelengths. It was pumped by rare earth material amplifiers to accomplish the remarkable speed. That’s likewise not cheap. The developers expect this to be in use mostly to send data over long distances. Rather than, say, allowing you to download video games instantaneously.
Nonetheless, the team feels the new 4-core optical fiber optic cable it produced is the most significant breakthrough. It’s also approximately the same size as a regular fiber optic cable. NICT believes it could readily integrate into current systems to provide significant speed improvements. “The standard cladding diameter, 4-core optical fiber can be cabled with existing equipment, and it is hoped that such fibers can enable practical high data-rate transmission in the near-term, contributing to the realization of the backbone communications system, necessary for the spread of new communication services Beyond 5G,” they announced in their paper.
