A group of researchers from two European universities said they have set a new data transmission world record by transmitting more than 1 petabit per second.
A team of researchers has reportedly set aThe international group from the Technical University of Denmark and Chalmers University of Technology in Sweden used a single light source to transmit 1.8 petabits per second.
"In the experiment, the researchers succeeded in transmitting 1.8 Pbit/s, which corresponds to twice the total global Internet traffic," they wrote."And only carried by the light from one optical source. The light source is a custom-designed optical chip, which can use the light from a single infrared laser to create a rainbow spectrum of many colors, i.e. many frequencies. Thus, the one frequency of a single laser can be multiplied into hundreds of frequencies in a single chip.
The colors are fixed at a specific frequency distance from each other like the teeth on a comb, which is"Each color can then be isolated and used to imprint data. The frequencies can then be reassembled and sent over an optical fibre, thus transmitting data. Even a huge volume of data, as the researchers have discovered," DTU explained.
However, he notes that the chip was not optimized for this particular application and that some of the characteristic parameters had been achieved by coincidence. "However, with efforts in my team, we are now capable to reverse engineer the process and achieve with high reproducibility microcombs for target applications in telecommunications," Company said.
