It does not matter which type of cable is used whether it is single mode cables or multi-mode cables the information is transmitted in the same manner. That is the information is transmitted in the same manner regardless of the cable being used. Since the inside of fiber optic cable is coated with a reflective service, total internal reflection is present within the fiber optic cable. If one wants to transmit information through the interior of the fiber optic cables, what one must first do is convert analog information into digital signals. That is analog data must firstly be converted into digital data or digital signals then one can use the interior of the fiber optic cables. Once this is done and the information has been converted, lasers are able to transmit the digital signals in the form of pulses of light.

Since 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 bouncing off is very important. The bouncing off the reflective surfaces of the fiber optic cable is very useful and 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 travelling and moving through the cable to its final destination.
