Scientists have achieved the fastest Internet speed in the world, enough to download 1000 HD movies in a fraction of a second using a single optical chip, a breakthrough that could help increase the capacity of network connections worldwide. According to the study, published in the journal Nature Communications, the new innovation could accelerate the telecommunications capacity of countries struggling with the demand for Internet infrastructure.
The researchers, including Bill Corcoran of Monash University in Australia, recorded a data rate of 44.2 Terabits per second (Tbps) from a single light source. The scientists said this speed was achieved by connecting their new device to existing fiber optic technology, used on the broadband Internet network.
“Initially, they would be attractive for super fast communication between data centers,” said Arnan Mitchell, co-author of the study at RMIT University in Australia, in a statement. They tested the transmission on 76.6 kilometers of optical fibers between RMIT & # 39; Melbourne City Campus and Monash University & # 39; s Clayton Campus. According to the scientists, the optical fiber loop is part of the ALIRT (Australian Lightwave Infrastructure Researchbed Testbed), which was created with investments from the Australian Research Council.
In the study, the researchers used their new device that replaces 80 lasers with a single device known as a micro-comb, which is smaller and lighter than existing telecommunications hardware. They explained that it works like a rainbow made up of hundreds of high-quality invisible infrared lasers from a single chip. Each of these lasers, the study says, is capable of being used as a separate communication channel.
The scientists placed the micro-comb in the ALIRT’s optical fibers and sent the maximum data to each channel, simulating the maximum use of the Internet, with more than 4 TeraHertz (THz) bandwidths. Although this micro comb was used in the laboratory, they said it is the first time it has been used in a field test.
With an unprecedented number of people using the Internet for remote work, socializing and streaming during blockades of corona viruses, the researchers said the trial reflected normal demand for Internet infrastructure in a few years. & # 39; This really shows that we need to be able to scale the capacity of our Internet connections & # 39; said Corcoran.
Based on the results, he believes that the fibers that are already part of the Internet infrastructure can be the backbone of communication networks now and in the future. “And we are not just talking about Netflix here: it is the broadest scale of what we are using our communication networks for,” he added. Corcoran said the data can be used for self-driving cars and future transportation, as well as helping medicine, education, finance and the e-commerce sector. David Moss, director of the Center for Optical Sciences at the University of Swinburne, said that in the ten years since he invented them together, micro comb chips have become an extremely important area of research.
According to Moss, micro-combs offer us a huge promise to meet the world’s insatiable demand for bandwidth. “This work demonstrates the ability of optical micro-combs to perform on demanding and practical optical communication networks,” wrote the scientists in the study.
