What is optical fibres? |
| Answer» 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.Optical fibres have become very important in high-speed communications, such as cable TV and high-speed broadband services. Information, in the form of pulses of light, is sent down bundles of optical fibres. Fibre optic cables are able to carry more signals than traditional copper cable telephone lines.Hope this will help u saba ??<br>Optical fibers are made of glass. These are glass fibers. Now for fiber optic communication glass fibers are simply not enough they have to be specially built for total internal reflection (TIR). To achieve TIR the optical fiber is given an outer layer having a lower refractive index called cladding and the central part of the glass fibre is called core. | |
