Question

3) Explain the construction of an Optical Fibre.​

Answer 1

$\large{\underline{\red{\bf{Answer:-}}}}$

➜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.

Answer 2

Answer:

It consists of a very thin fibre of silica or glass or plastic of a high refractive index called the core. The core has a diameter of 10 μm to 100 μm. The core and the cladding are enclosed in an outer protective jacket made of plastic to provide strength to the optical fibre. ...
