Researchers just set a new data transfer speed record

(ORDO NEWS) — Even if you enjoy great broadband speeds at home, wherever you live, you will still be very, very far from the new data transfer record: an incredible 1.02 petabits per second. p>

That’s a million gigabits shifting down a line every second. The record was set by a team from the National Institute of Information and Communications Technology (NICT) in Japan, which transmitted data over a distance of over 51.7 km (32 miles).

In other words, there is enough bandwidth. to transmit not just one 8K video stream or hundreds or thousands of 8K video streams, but 10 million 8K video streams simultaneously. That’s a lot for Netflix.

One of the exciting aspects of the new data rate record is that the researchers achieved it using a fiber optic network no different from those currently used for Internet infrastructure. The researchers say this should make it easier for future upgrades to reach that speed.

Just a year ago, researchers at the same institute were getting top speeds about a third of what they are now, demonstrating the rapid development of technology.

The experiment used a multi-strand fiber (MCF) with a diameter of 0.125 mm, with wavelength division multiplexing (WDM) acting as the magic ingredient: this technology means that signals with different wavelengths are transmitted. simultaneously across the line. A total of 801 parallel wavelength channels were packed into one line.

Another innovation was the use of four cores instead of the standard, which significantly increased the number of routes for data transmission by four times, while the cable remained the same. about the size of a standard fiber optic line. The researchers also applied various other optimization, signal amplification and decoding technologies.

In specialized experiments such as this one, there is usually a balance between distance and speed high speeds are more difficult to maintain over long distances. The team plans to keep improving transmission speed and transmission distance in their future research.

While the same group of researchers hit the petabits milestone back in December 2020, they used a more sophisticated technology that required more work to encode and decode the signals. The system used in this case is easier to implement in real physical networks, and it is more similar to the existing infrastructure.

As 5G also continues to roll out around the world, this suggests that the gadgets of the future will be favourable. connected to an always-on high-speed Internet connection, although the number of devices that need to connect to the Internet continues to grow rapidly.

“In addition to 5G, there is a dramatic increase in data traffic due to new information and communication services, and therefore it is critical to demonstrate how new fibers can meet this demand,” NICT said in a press release.

“It is hoped that this result will help implement new communication systems capable of supporting new bandwidth-demanding services.”

The research was presented in May at the International Conference on Laser and Electro-Optical Engineering (CLEO) 2022.
