Researchers have discovered a way to dramatically improve the reliability of high-speed internet. Fiber optic lines use light waves to transfer data, but sending high-speed long-distance communications requires a lot of power. The more power used to transmit a signal, the more interference, or noise, creeps in. A well-established way of dealing with the interference is by inverting the noise to its phase conjugate. As BBC News notes, the concept is similar to how active noise-canceling headphones work.
Noise-canceling headphones monitor the nearby environment with a microphone and generate the inverse signal of what they hear, preventing the noise from being audible. While it's a simple enough concept, there hasn't been an...
