Optical fiber is one of the effective means of telecommunications and computer networks because of its flexibility and its ability to be bundled into cables due to its thickness. The light inside the fiber propagates with little attenuation compared to the cable and is therefore advantageous for long distance communication. This allows very few repeaters to be used to span long distances. A repeater is an electronic device used to connect wires and long distances. It is important to connect the wires and make sure that there is a significant loss of successful communication when the light passes through them. Therefore, this connection is more complicated than the usual wires. Due to the well-known concept of total internal reflection, communication takes the form of light inside the fiber. This is due to the difference in refractive indices of the two media when the light propagates. The optical fibers are encapsulated in a fibrous polymer such as aramid in a plastic cover and connected at each end using a fiber optic connector. Fiber is considered to be the fastest communication medium, and it has been recorded that a single fiber can transmit 1015 bits/second in 50 kilometers. This is most advantageous for audio transmission, providing a wider bandwidth and very small attenuation over long distances. They are also used today for sensors and remote sensing. Different measurements can be made by changing the fiber, which is used to convert light into electricity and transmit power during times when it is desired to have no metallic conductors that generate a strong magnetic field. Other examples are used to power electronic devices in high power antenna components and measurement devices used in high voltage transmission devices. Fibers are very strong and they often lose strength due to fatigue or stress aging. In addition to glass optics, there are also plastic fibers for small distance translation.
