Which of the following is a benefit of fibre optic cables?

Fibre optic cables are known for providing more secure data transmission compared to other types of cables, such as unshielded twisted pairs (UTP). This enhanced security primarily arises from the nature of light transmission within the fibres. Data encoded in light signals is less susceptible to interception and eavesdropping, as it is difficult to tap into a fibre optic cable without detection. Additionally, fibres do not emit signals that can be easily monitored, making unauthorized access significantly harder.

Other benefits of fibre optic technology, while significant, do not directly address the security advantage. For instance, factors like power requirements and costs can vary, and while fibre optic cables can be lighter and more efficient in certain scenarios, this does not inherently provide a security benefit as strong as the encryption capability and the physical barriers that fibre optics offer.
