fiber cables operate using the principle of internal reflection.
The question is very silly, however, because qualities of fiber cables are
Positive qualities: great signal information rate (bandwidth) capability.
Negative qualities: signals of different frequencies travel at different speeds, so the received signals do not reach the destination at the same time. This causes great distortion. Attenuation: signals rapidly diminish in fiber cables, they have to be reconstituted and re amplified ever few miles with repeaters.
