Vedclass · Answer

(D) Attenuation in an optical fibre refers to the loss of signal power as light travels through the fibre. This loss is primarily caused by two factors: $1$. Absorption: The material of the fibre (glass) absorbs some of the light energy and converts it into heat. $2$. Scattering: Impurities in the glass fibre cause light to scatter in various directions,including sideways,which results in some light escaping the fibre core. Therefore,both absorption and scattering contribute to the attenuation of the signal.
