Lesson 7 of 13 • 1 upvotes • 10:18mins
Rajesh Kumar
Optical Fibre made by glass material and fibre means very thin thread like structure .in optical fibre light ray can travel without appreciable loss from one. To other. And go from one City to other City. the basic phenomena in optical fibre is total internal reflection. the materials of Optical Fibre is mainly divided in 3 part, the core most important part made of glass of high refractive index. core is insulated by some other plastic or glass material having less refractive index with respect to core material .and the outermost part is plastic material which bound optical fibre and give strength to the optical fibre .Optical Fibre mainly used in medical facility as endoscope, in communication to transmit information from one City to other City.
