Fiber optics is the science of transmitting data, voice, and images by the passage of light through thin, transparent fibers.
Fiber optics (optical fibers) are long, thin strands of very pure glass about the diameter of a human hair. They are arranged in bundles called optical cables that carry information between two places using entirely optical (light-based) technology.
So how do these tiny strands of glass transmit light? What happens if you tie the optical fibers into a knot? Watch the demo video to find out!
