Question

The optical fibre wires have replaced the copper wire as transmission cable since it has more advantages than the electric cables. Out of the following options, which one is seen to be a disadvantage rather than an advantage?
1. Delicate handling
2. Large transmission capacity
3. Easy amplification
4. Small losses

Answer 1

Correct Answer - Option 1 : Delicate handling

Analysis:-

Advantages of Optical fiber cables:

• Unlike copper wires where electrical signal transmits, in optical cables light signals are transmitted. It supports extremely high bandwidth and speed. It has a large transmission capacity.
• The optical fiber cables are thinner and lightweight as compared to Copper wire.
• It has very small signal losses as compared to Copper wires thus enabling easy amplification.
• Optical fiber cables have longer life spans.

Disadvantages of Optical fiber cable:

• A large number of repeaters are needed to keep the signal intact.
• They must be handled very delicately because they are more fragile and vulnerable to damage than copper wire.

So, we can say the disadvantage of Optical fiber cable over Copper wire is its need for delicate handling.
