Correct option is C
The statement "They are cheaper" is incorrect in the context of optical fibres. While optical fibres have numerous advantages over traditional copper wires, such as higher data transmission speeds and resistance to electromagnetic interference, they are more expensive to install and maintain.
Here’s a breakdown of why optical fibres are advantageous:
Longer connectivity: Optical fibres can carry signals over much longer distances compared to copper cables without significant loss of signal strength. This makes them ideal for long-distance communication networks, including telephones and the internet.
Less noisy: Optical fibres are immune to electromagnetic interference (EMI) because they use light to transmit signals, not electrical currents. This results in a much cleaner and less noisy transmission.
Longer life-time: Optical fibres are durable and resistant to harsh environmental conditions, which gives them a longer operational life compared to traditional copper wires.
