Answer 2

Answer:

An optical fiber is a cylindrical dielectric waveguide (nonconducting waveguide) that transmits light along its axis, by the process of total internal reflection. The fiber consists of a core surrounded by a cladding layer, both of which are made of dielectric materials.

STEP INDEX FIBER : The refractive index of the core is uniform throughout and undergoes on abrupt change at the core cladding boundary GRADED INDEX FIBER: The refractive index of the core is made to vary gradually such that it is maximum at the center of the core.
