Question

What are optical fibers? Mention their one application.

Answer 1

In the above question we have to find out what is optical fiber and also, we have to write the application of optical fiber too. We know that optical in physics means light so, it is something related to light and also fiber is used for transmission so, it is used for transmission of light.

Complete step-by-step solution:
Optical fiber is defined as the technology that is associated with the transmission of data using light pulses that travel along with long fibers which are usually made up of plastic or glass. Metal wires are usually preferred for transmission in optical fiber communication as we know that signals travel with fewer damages. Optical fibers are also often unaffected by electromagnetic interference. The fiber optical cable majorly uses the application of total internal reflection of light. The fibers are designed in such a way that they facilitate the propagation of light along with the optical fiber that depends upon the requirement of power and the distance of transmission. Single-mode fiber is commonly used for long-distance transmission, while the multimode fiber is commonly used for shorter distances. The outer cladding of these fibers needs more protection than metal wires. As we know that there is no loss of energy in total internal reflection, the light signal is transmitted by optical fiber without any appreciable loss of energy.
Now, we will discuss the main applications of Optical fibers they are communication systems, medicine, sensors, military, and electronics.
(1) The medical field fiber optics helps provide a very compact and flexible conduit for light or data delivery in the equipment, surgical, and instrumentation applications.
(2) Telecommunication fibers used as fiber optics are laid and commonly used for transmitting and receiving messages.
(3) Military or government care commonly used as hydrophones for the seismic and SONAR uses mostly as wiring in aircraft, submarines and other vehicles and also for field networking.
(4) Optical fiber is also used for transmission of light signals to distant places.

Note: We clearly know that the optical fibers are the thin strands of glass and the core use of optical fiber includes the transmission of the information in the form of light that is optics. The major use of optical fibers has genuinely proved beneficial when compared to the traditional use of metallic wires.
