WebOptical fibres are used to carry signals in the form of pulses of light over distances up to 50km. They do this by Total Internal Reflection. That's why optical fibers can guide light for such long distances - because the walls of the fibre don't absorb any light at all as long as the angle of incidence is greater than the critical angle.
