go figure be able to download all movies and series from Netflix in less than a second. Thousands of titles in an instant. Researchers from University College de Lonjersey they just set the record for internet faster: 178 terabits per second, 178.000 Gbps. The Royal Academy of Engineering professor and research fellow, Lidia Galdino, collaborated with Xtera and KDDI Research on the project.

According to the announcement of the UCL, that speed is “twice the capacity of any system currently deployed in the world.” To get that blazing fast speed, researchers from the UCL used a greater range of wavelengths than the typically used in fiber optic cables, as well as different amplification technologies to increase the signal. Fiber optic cables tend to absorb signals (well, the photons that are transmitted through the cable to make the signal) after a few kilometers due to the material the cables are made of. Repeaters, which are like a Wi-Fi extender, are needed to relay those signals so they can travel a longer distance. Thus, what the researchers managed to do is not only extend the signal, but also greatly amplify it..

The current infrastructure uses a limited spectrum bandwidth of 4,5 THz, pero a commercial bandwidth of 9 THz is starting to enter the market. He 5G in the millimeter wave or high band spectrum operates at 24 GHz or higher and can transmit data at a speed of 1 to 3 Gbps. But the Internet of Galdino reaches the 16,8 THz y 178.000Gbps, making 5G seem quite slow in comparison.

This type of system would also be cheap to integrate into our internet infrastructure existing. According to him UCL, improve amplifiers each certain intervals would cost a fraction of what it costs install new fiber optic cables, approximately 20,000 Dollars every 40-100 km versus $600.000 every 1 km. It looks like it could be a useful solution to help bridge the digital divide, something the pandemic has put even more in evidence.

“Regardless of the crisis of the covid-19, internet traffic has increased exponentially in the last 10 years, and all that growth in data demand is related to the decrease in cost per bit, ”said Galdino al UCL. “The development of new technologies is crucial to maintain this trend towards costs lower while meeting future data rate demands, that will continue to increase with applications not yet known that will transform people’s lives ”.

Internet traffic has increased because many now work or they attend school from home, besides there is increased demand for digital entertainmentsuch as streaming movies and games online. The internet remains strong for now, but many do not have reliable access or accessible to him, a problem that we dragged from before the current pandemic.

The study, titled “Optimization of fiber optic capacity through continuous bandwidth amplification and geometric shaping”, is available in IEEE Photonics Technology Letters .
