In a major breakthrough that can make the internet superfast and cheap, researchers have successfully increased the maximum power — and therefore distance — at which optical signals can be sent through optical fibres. The advance has the potential to make the internet superfast by increasing data transmission rates for the fibre optic cables — which serve as the backbone of the internet, cable, wireless and landline networks. A long-standing roadblock to increasing data transmission rates in optical fibre has been that beyond a threshold power level, additional power surge […]
