Which statement describes a difference between fibre and UTP connections?

• A. Fibre has a faster data transmission speed.
• B. UTP is immune to eavesdropping.
• C. Fibre is affected by EMI.
• D. UTP covers larger distances.

Answer: (A)

Fibre optic cables deliver data as light, which lets them carry far more information at higher speeds than copper twisted-pair (UTP). The light signal suffers far less loss over distance and can use a much wider range of frequencies, so practical networks can run at gigabit speeds and beyond with fibre. That fundamental difference is why fibre is typically much faster than UTP. The other statements don’t fit. UTP is not immune to eavesdropping—copper cables can be tapped more easily, so copper isn’t secure by default. Fibre isn’t affected by EMI, since light signals in glass aren’t disturbed by electrical noise, so claiming fibre is affected by EMI is incorrect. And UTP cannot cover larger distances than fibre; copper signals degrade more quickly over length, whereas fibre supports much longer distances without repeaters.
