Q:

The attenuation in optical fibre is mainly due to

A) Scattering B) Absorption
C) Both (a) and (b) D) Neither absorption nor scattering
 
Answer & Explanation Answer: A) Scattering

Explanation:

The reason for transmitting data over optical fibers, is because the speed of data transmission through optical wires are equal to the speed of light. The intense speed of data transfer speed, has lead to the use of optical fibers. The optical fiber uses the technology of transferring light beams, from one end to the other end of optical cables. The attenuation in optical fiber is due to Scattering. The reason why scattering is caused, due to the folding, in the wire.
