Researchers at AT&T have devised a way to increase the distance that large amounts of data can travel through a fiber-optic connection. The technique should allow 400-gigabit-per-second signals to travel for a distance of 12,000 kilometers—four times the previous distance possible — and it promises faster ocean-crossing transmission without adding more equipment. The feat is like sending 170 HD movies 12,000 kilometers — half-again as far as the distance from San Francisco to Tokyo.
