The transmission of data over the Internet at high speeds is becoming increasingly important in today’s world. To create the Internet of the future, researchers at the Danish Technical University (DTU) have developed a new method for transmitting more data over already installed fibers. Scientists have established new world record, reaching a transfer rate of 1.84 petaflops per second.

The DTU researchers used a new device called frequency comb (Frequency comb, loosely translated). The device is photonic chip capable of transmitting 1.84 petaflops per second over a distance of up to 7.9 km. The chip was manufactured by Chalmers University of Technology in Sweden and is capable of converting infrared radiation used for data transmission into a spectrum where each color represents an equivalent frequency.

Technology allows multiple data beams can be encoded and reintegrated into a single infrared laser, before sending by fiber optic cable. Without a frequency comb, it would take at least 1,000 laser beams to achieve the same speed with commercial equipment available today, the researchers say.

The method reduces energy consumption on the Internet

In addition to the high speeds, the researcher in charge of the project, Leif Katsuo Oksenlow, says this method also significantly reduces power consumption generated by the internet.

According to Leif, the project is an opportunity to create a high-quality Internet of the future. “In other words, our solution offers the ability to replace thousands of data center lasers that consume power and generate heat. We have an opportunity to do our part to create an Internet that produces a smaller carbon footprint.”

In the meantime, researchers will continue research and try to surpass the mark. It is still too early for the created solution to reach our communication systems. With what we currently have, it’s impressive to imagine what will be possible with data transfer rates greater than 1 petaflops per second.
