Fiber optics uses light instead of electrons to send information from point A to point B. The technology is much faster, not to mention more reliable over long distances, than traditional wires. But light tends to go in straight lines, and we need cables to go, well, wherever we want them to. How does fiber optic technology bend light to its will? The solution is actually pretty ingenious. Watch a demonstration of it below.
