Light travels through conventional optical fibres at about 200,000km per second – about two-thirds the speed it travels in a vacuum – because the signals are passing through solid glass.
When vast amounts of data are exchanged between computing centres hundreds or thousands of kilometres apart, this difference amounts to a substantial delay.
