Fiber Optic Cable
Fibre Optic Cables function as a light guide, guiding the light introduced at one end through to the other end.
The light source can either be a light-emitting diode or a laser.
The light source is pulsed on and then off and a receiver, which is light-sensitive, on the other end of the cable converts the pulses back into the digital ones and zeros.
Even laser light shining through fiber is subject to loss of strength.
The faster the laser fluctuates, the greater the dispersion.
In a situation where disperssion is to great, repeaters may be necessary to refresh the signal.
