This article examines the evolution of optical communication technologies through time, as well as its early failures. The various generations of optical fiber communication, as well as their characteristics, are then examined. Total internal reflection is discussed, as well as various kinds of fibers and their sizes and refractive index profiles, dispersion, and loss processes. Finally, the overall system of optical fiber communication is briefly discussed, as well as its benefits and drawbacks. Future optical fiber communication based on soliton is also emphasized. Optical fiber is a data transmission method that uses light pulses that travel through a long fiber, which is typically composed of plastic or glass. Metal wires are chosen for optical fiber communication transmission because signals move with less harm. Electromagnetic interference has no effect on optical fibers. The complete internal reflection of light is used in the fiber optical cable. The fibers are intended to aid in the propagation of light together with the optical fiber, depending on the power and transmission distance requirements. Long-distance transmission is done using single-mode fiber, whereas shorter distances are done with multimode fiber. These fibers’ outer coating need more protection than metal wires.
