Fiber optic technology would not be possible if it were not for the process known as total internal reflection. It is this process which guides the information, in the form of light, and allows it to be directed in the intended path of dispersal. Without total internal reflection, data would be lost or absorbed by external components and transmission of information in this method would not be possible. As the name implies, total internal reflection is a principle which completely surrounds the core of the optical fiber, thereby containing the signal within the core of the fiber.
