Optical fiber, new speed record: 1.53 petabits per second reached

A team of researchers from NCIT, the Japanese research center dedicated to the field of Information and Communication Technology (ICT), has created a New record for data transmission over optical fiber: 1.53 petabits per second. For a reference with a more common unit of measure, this is 191,250 gigabits per second, or 2,372 individual install files on Steam of Cyberpunk 2077. For another reference, it is estimated that so far the bandwidth occupied by the Internet is 1 petabit per second. . This new connection can handle all the internet traffic in the world with just one cable!

It’s not an absolute record: it recently hit 1.84 petabits per second, but using a very experimental and advanced optical chip. Here, however, scientists have accomplished a feat using a Standard “single core” optical fiber cable with a standard diameter of 0.125 mm; This means that this speed is compatible with existing infrastructures. Which, of course, means a sharp reduction in implementation costs.

Like all traditional fiber optic connections, the new system uses a single glass core to transmit data, but the light is first modified to form 55 separate data streams, or methodswhich carry different data. At the destination the streams are decoded to reconstruct the original data.

Therefore NCIT is the first to showcase 55-mode transmission technology. Just a few months ago, the same engineers managed to set a new record – 1.02 petabits per second, but using only four cores and four modes. The most amazing detail is that There is still room for improvementAccording to scientists, higher speeds can be achieved if the frequency range used for transmission is expanded.
