Researchers from Monash, Swinburne and RMIT universities have successfully tested and recorded Australia's fastest internet data speed, and that of the world, from a single optical chip—capable of downloading 1000 high definition movies in a split second.

Published in the prestigious journal Nature Communications, these findings have the potential to not only fast-track the next 25 years of Australia's telecommunications capacity, but also the possibility for this home-grown technology to be rolled out across the world.

They used a new device that replaces 80 lasers with one single piece of equipment known as a micro-comb, which is smaller and lighter than existing telecommunications hardware.
It is the first time any micro-comb has been used in a field trial and possesses the highest amount of data produced from a single optical chip.

To illustrate the impact optical micro-combs have on optimising communication systems, researchers installed 76.6km of 'dark' optical fibres between RMIT's Melbourne City Campus and Monash University's Clayton Campus.
Distinguished Professor Mitchell said reaching the optimum data speed of 44.2 Tbps showed the potential of existing Australian infrastructure. The future ambition of the project is to scale up the current transmitters from hundreds of gigabytes per second towards tens of terabytes per second without increasing size, weight or cost.
