Question

Advantages of optical fibres over electrical wires is:

• A. High band width and EM interference
• B. Low band width and EM interference
• C. High band width low transmission capacity and no EM interference
• D. High band width, high data transmission capacity and no EM interference

Answer 1

The correct option is D High band width, high data transmission capacity and no EM interference

Few advantages of optical fibres are that the number of signals carried by optical fibres is much more than that carried by the Cu wire or radio waves. Optical fibres are practically free from electromagnetic interference and problem of cross talks whereas ordinary cables and microwave links suffer a lot from it.
