What are the optical fibres? How do they work? |

Answer» Answer: An optical fiber An optical fiber is a thin fiber of glass or plastic that can carry light from one end to the other. The study of optical fibers is called fiber optics, which is part of applied science and engineering Light travels down a fiber optic cable by bouncing off the walls of the cable repeatedly. Each light particle (photon) bounces down the pipe with continued internal mirror-like REFLECTION. The light beam travels down the core of the cable Optical fiber is used as a medium for telecommunication and COMPUTER networking because it is flexible and can be bundled as CABLES. It is especially advantageous for long-distance communications, because infrared light propagates through the fiber with MUCH lower attenuation compared to ELECTRICAL cables. Explanation: |
