Vedclass · Answer

(D) The correct option is $(D)$.Optical fibres offer several significant advantages over traditional copper wires or radio wave communication.First,they provide a very high bandwidth,allowing for a massive amount of data to be transmitted simultaneously.Second,they have a high data transmission capacity,which is essential for modern high-speed internet and telecommunications.Third,optical fibres are made of glass or plastic,which are insulators,making them practically free from electromagnetic $(EM)$ interference.Unlike copper cables or microwave links,optical fibres do not suffer from signal degradation due to external electromagnetic fields or cross-talk between adjacent cables.
