Some of the characteristics of an optical fibre are as follows.
(i) This works on the principle of total internal reflection.
(ii) It consists of core made up of glass/silica/plastic with refractive index , which is
surrounded by a glass or plastic cladding with refractive index . The
refractive index of cladding can be either changing abruptly or gradually changing (Graded index fibre).
(iii) There is a very little transmission loss through optical fibres.
(iv) There is no interference from stray electric and magnetic fields to the signals through optical fibres.
