Fiber optic cables send information across multiple channels. If too much is sent over a long distance at high speeds, the signal distorts. Researchers have been working on how to de-scramble that information, especially since this could effect not only IoT but the internet in general. The UC San Diego team developed a “frequency comb,” an electronic filter that predicts and reverses physical distortions that would otherwise affect the signal. It allows them to send clear data over 7,000 miles of cable, breaking traditional capacity limits 20 times over.
