A team of researchers has reportedly set a new world record for data transmission.
An international group from the Technical University of Denmark (DTU) and Chalmers University of Technology in Sweden transmitted 1.8 petabits per second using a single light source.
In a release, DTU said it was the first in the world to transmit more than 1 petabit (equivalent to 1 million gigabits) per second using only a single laser and a single optical chip called a “frequency comb.” I’m here.
“In experiments, researchers successfully transmitted 1.8 picobits per second, which is double the global Internet traffic,” they wrote. “And it’s only carried by light from one light source. The light source is a custom-designed optical chip that uses light from a single infrared laser to generate a rainbow spectrum of many colors, or many frequencies. , so one single laser frequency (color) can be multiplied by hundreds of frequencies (colors) on a single chip.”

Colors are fixed at specific frequency distances from each other, like the teeth of a comb. Why is it called a frequency comb?.
“Then each color (or frequency) can be separated and used to imprint data. The frequencies can then be reassembled and sent over fiber optics to transmit the data. As the researchers discovered, a huge Even volume data,” DTU explained. .
Professor Victor Torres Company of Chalmers University of Technology said the chip has ideal properties for fiber optic communications, covering “high light output” and “broad bandwidth within the spectral region of interest for advanced optical communications.” Told.

However, he notes that the chip was not optimized for this particular application and some characteristic parameters were achieved by chance.

“However, the efforts of my team have enabled us to reverse engineer the process and achieve highly reproducible microcombs for telecom target applications.”
Researchers say the solution significantly reduces power consumption and could help reduce the Internet’s climate footprint.

“In other words, our solution offers the potential to replace hundreds of thousands of lasers deployed in internet hubs and data centers, all of which consume power and generate heat. , we have the opportunity to contribute to the realization of an Internet that leaves a smaller climate footprint,” said Professor Leif Katsuo Oxenløwe, director of DTU’s Center of Excellence for Silicon Photonics for Optical Communications.
However, he points out that some development work is still required to implement the solution in current communication systems.
