First of all, let us understand what an optical fiber is. Optical fiber is a fiber constructed of glass or plastic of a specific nature. It does not contain any metal material and thus avoids Electro-Magnetic Interference (EMI) and distortion of information along with the distance. This results in high accuracy of data along the transmission cable. The objective of fibre optic cable is to carry light waves along its length. The core technology for optical transmission is total internal reflection. Total internal reflection to ensures that the light is always along the body inner reflection material, so always keep a fiber in the body. As a result, the loss of signal is minimized, and hence the distance that the message can be carried without losing the signal is maximized. The light waves carrying the information along the channel have a path of propagation.
