Fiber optic cables allow bits to travel at the speed of light without any signal loss over long distances. true or false

answer:

true

explanation:

the low refractive index material that surrounds the core of an optical fiver and provides the optical refractive barrier and protection of the core; the transparent material, usually glass that surrounds the core of an optical fiber, causing any dispersed light to be reflected back into the central core, thereby to maintain signal strength over long distances.

carbon atoms, hydrogen, oxygen, and nitrogen.
