It is also used in other industries, including medical, defense, government, industrial and commercial. Optical fiber is used by telecommunications companies to transmit telephone signals, Internet communication and cable television signals. converting it into an electrical signal.relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak.creating the optical signal involving the use of a transmitter, usually from an electrical signal.The process of communicating using fiber optics involves the following basic steps: Because of its advantages over electrical transmission, optical fibers have largely replaced copper wire communications in backbone networks in the developed world. Background įirst developed in the 1970s, fiber-optics have revolutionized the telecommunications industry and have played a major role in the advent of the Information Age. Researchers at Bell Labs have reached a record bandwidth–distance product of over 100 petabit × kilometers per second using fiber-optic communication. Optical fiber is used by many telecommunications companies to transmit telephone signals, internet communication, and cable television signals. This type of communication can transmit voice, video, and telemetry through local area networks or across long distances. Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference is required. The light is a form of carrier wave that is modulated to carry information.
