Japanese researchers once again The record speed of data transmission of optical fiber cables They broke the standard. All the traffic in the world is transmitted in a fiber optic cable.
The Japanese team succeeded Breaking the data transfer speed record Standardized using fiber optic cables. Using a new technique, the team was able to simultaneously transmit a high volume at a speed of 1.53 petabits per second.

Record speed of information transmission in the hands of Japan!
Researchers recorded this record by using information encoding technique in 55 different optical frequencies. The rate of this bandwidth has now increased to such an extent that it is no longer impossible to carry the entire Internet traffic (which is roughly less than a petabit per second) over a single fiber optic cable. To understand this figure, you need to know that it is about a million times more than the best possible bandwidth that is available to the public.
The mentioned technology uses different frequencies of light that exist throughout the light spectrum. Each color in the spectrum of visible and invisible light has a specific frequency and with this frequency it can carry a specific flow of information. By using these frequencies and their efficiency, the researchers succeeded in reaching a high speed 332 bps/Hz became
With this method, information is transmitted through 184 different wavelengths. In addition, adjustments are made before sending light in the cable that can transmit 55 separate data streams.
In this method as well (just like most fiber optic cables), information is transmitted through a glass fiber. When the information reaches its destination, the receiver starts decoding the wavelengths to obtain the data. In the experiment conducted by Japanese researchers, the distance between the transmitter and the receiver was 25.9 km. Of course, this is not the end of the story, so the Japanese researchers announced that this method has the potential for further improvement. The results of this research were presented at the European Optical Communication Conference for the first time.
