A group of scientists from the Australian University of Monash University, as well as the universities of Swinburne University and RMIT University (also Australia) using a single optical chip
were able to achieve a record Internet connection speed of 44.2 Tb / s. At this speed, for example, users can download 1,000 movies in HD quality in a split second.
Researchers were able to load test the network using part of Melbourne’s existing fiber-optic communication infrastructure – 76.6 km of “dark” optical fibers laid
between the RMIT campus in Melbourne and the Monash University campus in Clayton. To optimize the network, scientists used a new device known as microcomb (micro comb) – an optical device
based on an ultra-miniature photon microcircuit, which is much smaller and lighter than existing telecommunication equipment – its dimensions are only about 3×5 mm. Within
The microcomb project was first tested in the field using existing infrastructure. The microcomb chip consists of hundreds of infrared lasers, each of which can be
used as a separate communication channel. Researchers were able to transmit the maximum amount of data for each channel, simulating peak loads on the network.
“The possibilities of using micro-comb for organizing fiber optic telecommunications with ultra-high bandwidth are quite real. Our work, within the framework of which was set
the world record for the throughput of one optical fiber from a single source – a chip – represents a huge breakthrough and provides the broadest prospects for satisfying truly
an insatiable global demand for bandwidth, ”said Professor David Moss of Swinburne University, one of the study’s leaders.
Test results were published in the prestigious journal Nature Communications, as well as on the official website of Swinburne University. By
the forecast of scientists who led the study, the established record for Internet connection speed can not only accelerate the development of Australia’s telecommunication potential over the next 25
years, but also provide the opportunity to spread new technology around the world. The latter is able to support high-speed Internet access for both 1.8 million households in Melbourne and
for billions of users worldwide during peak periods.
“The goal of the project is to increase the current transfer capacity from hundreds of gigabytes per second to tens of terabytes per second without increasing the size, weight or cost of network equipment.
In the long term, we hope to create integrated photon chips that could provide such a data transfer rate over existing fiber-optic communication lines with
at the lowest possible cost, ”comments project co-author Professor Arnan Mitchell of RMIT. – In the initial stages, they could be used to provide ultra-high speed
communication between data centers. However, one can imagine that this technology will become cheap enough and compact for widespread commercial use around the world. ”
“An unprecedented number of people using the Internet today for remote work, communication and streaming, showed us that we should be able to scale the capabilities of our
Internet connections, – comments one of the authors of the project, Dr. Bill Corcoran of Monash University. – Our study demonstrates the ability already
existing fiber-optic infrastructure will become the basis for scalable communication networks of the future, which will be able to satisfy all future needs. It’s not just about Netflix,
but also about the wider use of communication networks – for vehicles of the future, for medicine, education, finance and e-commerce, and much more. ”
