innovation. Researchers from the Japanese National Institute of Information and Communication Technologies (NICT) broke the Internet speed record with 319 terabits per second. According to a report by Canadian electronic journal Vice.com, this is more than double the previous record of 178 TB/s set a year ago by engineers in Japan and the UK.
“The combination of rare earth minerals, a new type of fiber optic cable and a sophisticated laser system has pushed the data at a speed never seen before,” the site says.
The speed test was done in a Japanese laboratory using advanced fiber optic technology. Many fiber optic cables consist of a core and multiple coatings, which protect the data from the inside. “The ICT system used an experimental strand of fiber optic cable, with four cores placed in a cable roughly the size of a standard fiber optic line,” added the same source.
“4-core fiber [multi-cœurs] Initial fibers with a standard sheath diameter are attractive to adopt [de multiplexage par répartition spatiale] in long-distance broadband links, as they are compatible with traditional cable infrastructure and should have reliability comparable to single-mode fibres,” NTIC said in an article on the experiment.
As a reminder, NTIC looped the data through coiled pieces of fiber optic, which simulated a transmission distance of 3,001 km, or about 1,864 miles, without any degradation in signal or speed. The researchers used a 552-channel comb laser firing at multiple wavelengths and pushing it through amplifiers made of rare earth minerals to achieve incredible speeds.
