New Fiber Optic Cable Sets World Record at 1 Petabit per Second

Key Takeaways

1. A new global record for data transmission was set at 1.02 petabits per second over 1,808 kilometers using a 19-core optical fiber.
2. The new fiber optic line has a transmission capacity of 1.86 exabits per kilometer per second, surpassing the previous record of 1.71 exabits per kilometer per second.
3. The research team was led by the National Institute of Information and Communications Technology (NICT) in Japan.
4. An optical amplifier was integrated to extend the transmission range to nearly 2,000 kilometers.
5. The team aims to address future data traffic demands and improve optical amplification efficiency with this new technology.

Data transmission reached an astonishing rate of 1.02 petabits per second over a stretch of 1,808 kilometers, marking a new global record set by a team of international researchers. They employed a newly engineered standard 19-core optical fiber, which showcases low losses across various wavelength bands.

Previous Achievements

Earlier this year, in March 2023, a standard 19-core fiber optic cable achieved a transmission speed of 1.7 petabits per second, but this was only effective over a distance of a little more than 60 kilometers. The newly developed fiber optic line boasts a much higher transmission capacity of 1.86 exabits per kilometer per second, surpassing the former world record of 1.71 exabits per kilometer per second set in October 2023.

Innovative Techniques

The team, guided by the National Institute of Information and Communications Technology (NICT) in Japan, utilized a standard-diameter fiber optic cable featuring 19 cores that were linked together. By integrating an optical amplifier, the team was able to extend the transmission range to nearly 2,000 kilometers.

The researchers aspire that the introduction of this type of 19-core fiber optic cable will effectively manage the rapidly growing amounts of data traffic expected in the future. Additionally, the research team is keen on advancing the efficiency of optical amplification and discovering practical uses for this new technology.
