How is information transmitted through a Fiber Optic cable?
Regardless of which type of cable is used, information is transmitted in the same manner. Because the inside of fiber optic cable is coated with a reflective service, total internal reflection is present within the fiber optic cable. In order to transmit information through the interior of the fiber optic cables, analog information must first be converted into digital signals. Once this information is converted, lasers are able to transmit the digital signals in the form of pulses of light. Because there is total internal reflection within the fiber optic cables, the information that is being transmitted in the form of light is able to continuously bounce off the reflective surfaces of the fiber optic cable. This is important, because even when the fiber optic cable is laid through an area that requires it to bend or twist, the total internal reflection allows the light to continue traveling through the cable to its final destination.
