A new record for data transfer speed over conventional fiber is set – 44.2 Tbps


Researchers from the Australian universities of Monash, Swinburne and Melbourne during the experiment set a new speed record for data transmission using optical fiber. This data rate was 44.2 Tb / s or 5.525 TB / s.

To understand: at this speed, you can transfer the contents of 50 Blu-ray Ultra HD discs with a capacity of 100 GB each in just one second.

Preparations for the experiment began with laying 75 kilometers of conventional fiber-optic cable between the campuses of the Royal Melbourne Institute of Technology, Swinburne University of Technology and Monash University.

To achieve a record speed, specialists used the new microcell technology, which provided more efficient data transmission. These microcells are generated inside the cable’s fiber by integrated microplane resonators. According to the researchers, the technology was first tested in real conditions.

“Our experiment demonstrates the capabilities of existing fiber lines. They can be the basis for not only current, but also future communication networks. Our development is scalable and able to meet future needs. ”, – noted one of the authors of the study and lecturer at Monash University, Bill Corcoran.

Now scientists are thinking about how to integrate the technology they developed into the existing infrastructure. “In the long term, we hope to create integrated photonic chips that will achieve such a data transfer speed through existing fiber optic communication channels with minimal cost””, Added Arnan Mitchell, a professor at the Royal University of Technology, Melbourne.

However, to use such a data transfer rate at home in the near future will not work. According to the researchers, even if the technology “gets on a commercial footing,” the first ones who can use it are likely to be data centers. In the end, gigabit Internet has been around for a long time, but it is still not found everywhere. Nevertheless, experts add, if the new technology becomes cheap enough, then one day it may become available to ordinary consumers.
