1 Unlike cable, fiber is not easily affected by water. Fiber-optic technology is practically weather-proof.  Fiber optics use light to transmit information, so the networks can transmit more information between the central office and the home - faster. This means faster fiber-optic Internet speeds, sharper fiber-optic television and clearer calls with fiber-optic home phone.
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 and used to transmit light signals over long distances.If you look closely at a single optical fiber, you will see that it has the following parts:1  Core-Thin glass center of the fiber where the light travels.hey are arranged in bundles called optical cables and used to transmit light signals over long distances.
