Whatever type of cable is used, information is transmitted in the same way. Because the interior of the fiber optic cable is coated with a reflection, total internal reflection is present in the fiber optics. In order to provide information within the fiber optic, analog information must first be converted into digital signals. Once this information is converted, lasers can transmit digital signals in the form of pulses of light.
Because there is total internal reflection within the fiber optics, information that is transmitted in the form of light is able to constantly bounce off the reflective surfaces of the fiber. This is important because even when the fiber optic cable is defined by an area which requires that bend or twist, the total internal reflection allows the light to continue traveling through the cable to its final destination.
