Radio takes less time because it takes a direct, straight path from point to point. An optic fiber will always have a longer path.

- woliveirajr 9y agoAnd that's correct... inside the optic fiber, the light doesn't go straight in the core of the fiber. It bounces and is reflected, making the path longer.
