Scientists have achieved a data transfer speed that we can only dream of at home.
Hungary has traditionally done well in terms of the speed and development of its residential broadband internet, but there are perhaps a few people who would say no to a few extra gigabits, and scientists have now proven again how long this particular limit can last.
That’s it 6 months laterthat Japan’s NICT Research Institute broke the speed of 1 bit (1 million gigabits) per second, scientists from the Technical University of Denmark and Chalmers University of Technology in Sweden worked together to nearly double the record.
The It has been published in the scientific journal Nature Photonics According to their study, the team achieved a data transfer rate of 1.84 Pbit/s in one second, which is twice the total global internet traffic.
Scientists have developed a new optical chip for this purpose: the structure, which acts as a “frequency comb,” splits the incoming light into hundreds of rainbow spectra of different colours, each encoded with data by modulating certain properties of the light (amplitude, phase, polarization).
Hundreds of specially modified frequencies are then combined into a single packet which is sent over a fiber optic cable and decoded at the other end. During the experiment, an amazing amount of data was transmitted over a distance of 7.9 km using this method.
At the same time, the Danish-Swedish team warns that there is still plenty of room for experimentation, because in theory a bandwidth of 100 Pbit / s is also available, which is 12,500,000 GB per second.
