Fibre-optic cables, such as those used in internet infrastructure, could be used for eavesdropping. A device that can pick up tiny changes in signals sent through the cables can detect words ...

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 ...

Fibre-optic cables can be used to detect earthquakes and other ground movements. The data cables can also pick up seismic signals from hammer shots, passing cars or wave movements in the ocean.

Fibre-optic technology, with its capability to transmit data at the speed of light, significantly outpaces traditional copper lines, says Zoom Fibre.

Scientists have transmitted quantum and conventional internet data through the same fiber-optic channel, meaning a future quantum internet could theoretically use existing infrastructure.

African governments should give fibre optic cables greater protection from attacks and harmonize policies around layouts to encourage the development of tech infrastructure, a Google executive ...
