World's fastest internet speed

World's fastest internet speed
Researchers from Monash, Swinburne and RMIT universities in Australia have successfully tested and recorded world fastest internet data speed of 44.2 Terabits per second(Tbps) from a single optical chip.
Researchers used new device that replaces 80 lasers with micro-comb,which is
single piece of equipment.It is smaller &lighter than existing telecommunications hardware.They placed micro-comb onto ALIRT's optical fibres and sent maximum data in each channel,simulating peak internet usage across 4 THz of bandwidth.
It is first time that micro-comb has been used in field trial.
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. The optical
 fibres were provided by Australia's Academic Research Network.
