Q96 / 120 · VITEEE 2010 · Physics

The attenuation in optical fibre is mainly due to

A
absorption
B
scattering
C
neither absorption nor scattering
Correct answer
D
Both (a) and (b)

Solution

From an optical fibre due to absorption or light leaving the fibre area resulting scattering of light sideways by impurities in the glass fibre. And due to this reason a very small part of light energy is lost.

Hence, the correct answer is option: 'D'.
