Download 1,000 HD movies in just a fraction of a second. Do you think it’s impossible? Better to reconsider. Researchers from three Australian universities achieved the incredible connection mark of 44.2 terabits per second with a structure of “dark” optical fibers mounted between the campuses of the Melbourne Royal Institute of Technology (RMIT) and Monash University, with distance of about 22 kilometers between institutions.

Called microcomb, the installation replaces the standard group of about 80 lasers found in the most advanced telecommunications equipment. According to Phys.org, the novelty, compatible with optical fiber lines already available, generates lines of precise and equidistant frequencies through small microphotonic chips.

Such compatibility represents a substantial cost reduction, since, according to one of the researchers, Bill Corcoran, the backbone of the networks already installed would not need to be replaced. Companies specializing in cloud and internet of things services can benefit greatly from the solution. In addition, this is quite a step towards improved connections dedicated to the general public.

A collective initiative for the future of telecommunication
Another institution involved in the research was the Swinburne University of Technology, which provided the chip used between the fibers. It basically acts like a rainbow, made up of hundreds of high-quality infrared lasers. It is possible to dedicate each laser to a separate communication channel, optimizing the connection.

The peak was reached from a simulation of sending as much data packets as possible for each channel generated. “This is just a sample of how the Internet should behave within two or three years – when looking at the unprecedented number of people using the network for remote work, socialization and streaming. We need to adapt to these demands, ”said Bill.

Arnan Mitchell, a professor at RMIT, adds that future goals should focus on increasing current transmissions from hundreds of gigabytes per second to tens of terabytes without expanding the structures and costs involved.

Corcoran concludes: “We are not just talking about Netflix, but about a broader evolution in the way we use connections. Autonomous vehicles, future transportation, medicine, education and financial and e-commerce institutions can use these improvements. This will even allow us, for example, to connect even more with our grandchildren even though we are miles away ”.
