Scientists Develop ‘New’ Optical Fibre to Capture Fastest Internet Speed

Researchers from the National Institute of Information and Communications Technology in Japan have developed a 4-core optical fibre to record the world’s fastest internet speed. They claim to have succeeded the first S, C and L-bands transmission over long-haul distances in a the optical fibre.

The team lead by Benjamin J. Puttnam, constructed a transmission system that makes full use of wavelength division multiplexing technology by combining different amplifier technologies, to achieve a transmission demonstration with date-rate of 319 terabits per second, over a distance of 3,001 km. Using a common comparison metric of optical fibre transmission the data-rate and distance produce of 957 petabits per second x km, is a world record for optical fibres with standard outer diameter, the researchers claimed.

Researchers hope that such fibres can ”enable practical high data-rate transmission in the near-term, contributing to the realisation of the backbone communications system, necessary for the spread of new communication services beyond 5G.”

The results of this experiment were accepted as a post-deadline paper presentation at the International Conference on Optical Fiber Communications (OFC 2021).

NICT said, they will continue to develop wide-band, long-distance transmission systems and explore how to further increase transmission capacity of low-core-count multi-core fibres and other novel SDM fibres.
