A team of researchers from NCIT, the Japanese research center dedicated to the field of ICT (Information and Communication Technology) has established a new data transmission record on optical fiber: 1.53 petabits per second. For a reference with a more familiar unit of measurement, this is 191,250 gigabytes per second, or 2,372-odd installation files on Steam of Cyberpunk 2077. For another reference, it is estimated that to date the entire bandwidth occupied from the internet is 1 petabit per second. This new connection could handle all the world’s internet traffic with just one cable!
It is not an absolute record: in recent times it has even managed to reach 1.84 petabits per second, but using a very advanced and experimental optical chip. Here, however, scientists have accomplished a feat with a very normal “single-core” fiber optic cable, with a standard diameter of 0.125 mm; this means that this speed is compatible with current infrastructures. Which of course means a drastic reduction in implementation costs.
Like all traditional fiber optic connections, the new system uses a single glass core for data transmission, however the light is first modulated to form 55 separate data streams, or ways, which carry different data. At the destination the streams are decoded to reconstruct the original data.
NCIT is therefore the first demonstration of 55-mode transmission technology. Just a few months ago, the same engineers had managed to set a new record – 1.02 petabits per second, but using four cores and only four modes. The most amazing detail is that there is still room for improvementAccording to scientists, even higher speeds can be achieved if the frequency band used in transmission is widened.
