Which of the following is a benefit of using a fiber-optic cable?

Using fiber-optic cables offers significant advantages in terms of security, particularly resistance to wiretapping threats. Fiber-optic cables transmit data as light through glass or plastic fibers, making it extremely difficult for unauthorized individuals to tap into the lines without being detected. Unlike copper cables, which can be easily tapped or intercepted, any attempt to physically tap a fiber-optic cable typically results in the disruption of the light signal, signaling that tampering has occurred. This inherent feature provides a higher level of security for data transmission, making fiber-optic solutions ideal for environments where data integrity and confidentiality are essential.

Other options, while they may present benefits in different contexts, do not directly align with the security advantage of fiber-optic technology. For example, while fiber-optic cables can offer better performance in high electromagnetic areas, this is not primarily a security feature. Similarly, the installation process may not necessarily be easier than that of copper cables, and fiber-optics generally come with a higher initial cost compared to copper. All these factors highlight that the resistance to wiretapping is a distinct and critical benefit of using fiber-optic cables.
