Vedclass · Answer

(C) Signal attenuation in an optical fiber refers to the loss of optical power as light travels through the fiber. The primary mechanisms responsible for this attenuation are: $1$. Absorption: This occurs due to the presence of impurities in the glass (like $OH^-$ ions) and the intrinsic properties of the material,which convert light energy into heat. $2$. Scattering: This is primarily caused by Rayleigh scattering,which arises from microscopic variations in the density and refractive index of the glass material during the manufacturing process. Therefore,both absorption and scattering are the main causes of signal attenuation in optical fibers.
