Fiber optic cables are constructed using glass or plastic and are designed to transmit data as light signals. This unique characteristic makes them inherently more secure against wiretapping threats compared to other types of cabling.

The core advantage of fiber optic technology lies in its method of data transmission. Since data is communicated through light, it is incredibly difficult to intercept or tap into the signal without detection. Any attempt to physically access the cable for tapping would require cutting into the fiber, which would likely disrupt the signal and alert users to a potential breach.

Additionally, fiber optic cables do not emit electromagnetic signals, unlike copper and coaxial cables, which can leak information and are more vulnerable to interception through methods such as electromagnetic eavesdropping. The resistance to external interference and minimal risk of data loss during transmission further enhance the security aspects of fiber optic cables, making them the preferred choice for sensitive data communications in secure environments.

Thus, the nature of fiber optics, paired with the security measures inherent in their design, solidifies their position as the least susceptible option to wiretapping threats among the choices provided.
