The attenuation in optical fibre is mainly due to

Options

  1. Aabsorption
  2. Bscattering
  3. Cneither absorption nor scattering
  4. DBoth (a) and (b)

Correct answer

D. Both (a) and (b)

Step-by-step 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.
