If telecommuting becomes the new norm for many around the world, high Internet speeds are now a necessity. Thinking about it (or not), a team of engineers in Japan has now achieved the fastest data transfer ever, with its record-breaking and unquestionably impressive internet speed.
The marvelous feat has been achieved by engineers at the National Institute of Information and Communication Technology of Japan (NICT) and has now been published in a research paper at the International Conference on Fiber Optic Communication held virtually June 6-11.
As mentioned in the survey, the NICT team recorded a speed of 319 terabits per second (Tb/s) for data transfer over a distance of approximately 3,000 kilometers. To put the new speed into perspective, just realize that the previous record for fastest data transfer was 178 Tb/s. The new technology beats old Internet speeds by using 4-core optical fiber with a standard 0.125mm outer diameter to transfer data using light instead of normal copper cables.
To do this, the team used a 552-channel laser that operates at various wavelengths. An experimental setup of a recirculating transmission loop that employed two types of fiber amplifiers. Specialized amplifiers helped increase the reach and speed of the Internet.
The team recorded the fastest data transfer ever, with no drop in performance over the 3,000 kilometer distance. Interestingly, engineers claim that the regular fiber-optic cables employed for Wi-Fi in our homes can also support this technology, although some modifications may be necessary.
The NICT noted that the new record Internet speed test results would help build new communications systems that can support the new “bandwidth-consuming services.” The team also said it would work even harder to increase the transmission capacity of “low-core count multi-core fibers and other new SDM fibers”.
This means that future data transfers can be even faster than re-registration. In addition to the improved speed, the NICT will also work to extend the transmission range “to transoceanic distances”.
