According to the report, data transfer speed over fiber has reached 2000 402 terabits per secondFor this measure, scientists from Aston University in Great Britain used the full range of wavelengths available in commercial fiber optic cables, while most such links typically use only one or two wavelengths.

The new record beats the previous record set in March by the same group of scientists, who achieved speeds of 301 terabits per second using four of the six wavelength ranges in previous experiments.

This finding could help increase the bandwidth of a single fiber so that the world can have a higher-performance system. The newly developed technology is expected to make a significant contribution to expanding the bandwidth of optical communication infrastructure due to the rapidly increasing demand for future data services.
– says Ian Phillips, lecturer in electronics and computer engineering at Aston University.

The research group is trying to reach a new record The world’s first optical transmission system covering all six wavelength bandsUsed in fiber optic communications, including O, E, S, C, L, and U. They belong to various parts of the infrared range of the electromagnetic spectrum, which lies between 1260 and 1675 nanometers. For comparison, visible light is in the range of 400 to 700 nanometers.

Most modern commercial fiber optic links transmit data using segments C-band And L rangeThese are the most stable sections, meaning the least amount of data will be lost during transmission. However, the researchers noted in their report that increasing network load means that these bands will one day become saturated, meaning we will need to use new bands.

• In the past, the S band adjacent to the C band was already used to enhance data transmission.
• Later, some of the E series was added to these. Usually, during transmission in this range, data loss increases to an extremely high level (five times). This is because fiber optic cables are sensitive to hydroxyl (OH) molecules in the soil, which can enter the tubes and disrupt the connections.
• Now scientists have created a device that will include O and U bands, amplifying the signals of the latter and using already existing amplifiers for the former.
