Splitting data into a spectrum of colour packets has enabled a single computer chip to transmit a record 1.84 petabits of data per second via a fibre-optic cable.
A single computer chip has transmitted a record 1.84 petabits of data per second via a fibre-optic cable – enough bandwidth to download 230 million photographs in that time, and more traffic than travels through the entire internet’s backbone network per second.
Asbjørn Arvad Jørgensen at the Technical University of Denmark in Copenhagen and his colleagues have used a photonic chip – a technology that allows optical components to be built onto computer chips – to divide a stream of data into thousands of separate channels and transmit them all at once over 7.9 kilometres.
Much more data could be sent through fibre-optic cables if it were split into different packets within each strand
