Vedclass · Answer

(D) Optical fibers operate on the principle of Total Internal Reflection $(TIR)$.They are made of high-quality glass or plastic,which allows light to travel long distances with minimal attenuation.Therefore,optical fibers have very low transmission loss compared to copper wires.They are also immune to electromagnetic interference because they transmit light signals rather than electrical signals.Thus,option $D$ is the correct statement.
