How do fiber optic cables work?
Fiber optics uses light to transmit signals. This way, they operate fast and have higher bandwidths. Also, they are not prone to electromagnetic interference. Fiber optic cables are of three kinds. These are single mode, multimode and POF. The first one uses single stand of glass fiber. Multimode operates through many cables and none is dependant on other for movement of light across it.
Fiber optic is just a light guide, one which connects light through to the exit point of the tunnel, once the light enters from one side of the tunnel. Light that we talk about here can be LED or Laser. The source of light works on a pulse and the receiver at the exit ends converts the pulse into digital signals. Fiber optics uses strengtheners to refresh the signals. This prevents dissipation of light traveling through the tube in form of Laser.
