According to a paper presented at the International Conference on Optical Fiber Communications in June, Engineers in Japan just make a new world record for the fastest internet speed, attaining a data transmission rate of 319 Terabits per second (Tb/s), The record was made on a line of fibers more than 1,864 miles (3,000 km) long. This could change everything across the Globe.
The recorded transmission speed is about twice as fast as the last record of 178 Tb/s, which was made less than a year ago & 7 times faster than the last record of 44.2 Tb/s made by an experimental photonic chip.
The American space agency NASA itself uses speed of 400 gigabits per second (Gb/s). But the new record increases above the current speed available to the users in areas of Japan, New Zealand & the United States, the fastest home internet connections reach 10 Gb/s.\
This new accomplishment was made conceivable by joining existing fiber optic framework with further developed advancements.
Rather than using the traditional basic core, the research group used 4 “cores,” which are glass tubes placed in the fibers that communicate data.
They use wavelength division multiplexing (WDM) technique, in which the signals are then split into several wavelengths & transmitted at the same time. To carry additional data, a seldom-used third “band” is added, & the distance is expanded using a variety of optical development technologies.
According to Japan’s National Institute of Information & Communications Technology (NICT), the signal motifs are then led into a new piece of optical fiber, & the crew of Japanese researchers were able to transmit data over 3,001 kilometres by repeating this procedure.
The new system begins the broadcasting process with a 552-channel cam laser shot at various wavelengths.
Japan’s primary national research institute for information & communications NICT said that they would “continue to develop wide-band, long-distance transmission systems & explore how to further increase the transmission capacity of low-core-count multi-core fibers & other novel SDM fibers. Further, we will work to extend the transmission range to trans-oceanic distances”.
Though, not only have Japanese scientists blasted the 2020 record out of the water, but they have accomplished so with a innovative technological solution that could easily be incorporated into the modern fiber-optic infrastructure.
