Japan achieves a new milestone by bringing the world closer to the internet 100,000 times faster than it is now

Japanese researchers have set a global record for data transmission using conventional technology, hitting rates 100,000 times faster than 5G internet speeds.

The Network Research Institute at the National Institute of Information and Communications Technology (NICT) demonstrated the first-ever data transmission of 1.02 petabits per second (PB/s), or just over 125,000 gigabytes per second (GB/s), using optic fibers compatible with existing cable infrastructure.

The transmission system was built by NICT utilizing conventional 0.125mm cladding diameter fibers, which it called "a critical step towards the realization of ultra-high-throughput optical networks... suitable for use with existing cabling technologies in the foreseeable future."


According to NICT, the system allows for the transmission of 1.02 PB per second over a distance of 51.7 kilometers.

NICT set a global record of 1 petabit per second in December 2020 with non-standard equipment, but signal processing made large-scale deployment impractical.


According to the Asian news site Next Shark, the transmission speed would allow for simultaneous broadcasting of 10 million distinct 8K films.

"Demand for increased data transmission capacity has prompted research into novel spectral transmission windows and sophisticated optical fibers that take use of parallelization in the spatial domain," according to NICT researchers.

"Advanced fibers with the same cladding width as normal single-mode optical fibers but capable of supporting multiple propagation routes have been proposed in recent years."

"These fibers have emerged as a likely choice for near-term commercial deployment of these disruptive communications technology because they can increase transmission capacity while being compatible with conventional production methods."

At the International Conference on Laser and Electro-Optics (CLEO) 2022, a paper describing the data transmission record was presented.
