Engineers in Japan have set a new world record for fastest internet speed – 319 terabits per second (Tb/s). It’s so fast, you’d be able to download nearly 80,000 movies in just one second! Typical fibre broadband cables have one core (which carries the data at high speeds), surrounded by insulation to protect that core and make sure that the data transmission does not break. Researchers at Japan’s National Institute of Information and Communications Technology developed an experimental optical fibre with four cores instead of one, combined with a laser that fired pulses at different wavelengths and multiple signal amplification techniques.
The findings of the research have now been presented at the International Conference on Optical Fiber Communications.
“The 4-core MCF with standard cladding diameter is attractive for early adoption of SDM 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,” the Japanese research institute said the paper published earlier this month.
The biggest positive outcome of the research was that the test was largely done on fibre optic infrastructure, which is already the main cable for internet connection in most countries.
