What are fiber optics?

Fiber optics are long, thin strands of glass roughly the diameter of a human hair. They are arranged in bundles that create a fiber optic “cable” and use light instead of electricity to carry a signal. These light signals represent data, which is capable of traveling at the speed of light. Fast Fact: One bundle of fiber optic cable, not much thicker than a pencil, can carry ALL of the world’s current communications traffic. (Source: FTTH Council)
