How do fiber-optic cables provide security for data transmission?

Fiber-optic cables provide enhanced security for data transmission primarily due to their ability to offer alternative routing that is more challenging to tap into. Unlike traditional copper cables, which can be easily intercepted, fiber-optic cables transmit data as pulses of light, making it difficult for unauthorized individuals to access the signals without being detected. Any attempt to tap into a fiber-optic cable typically disrupts the light transmission, alerting network administrators to potential security breaches.

Additionally, the physical properties of fiber-optic cables make them less prone to eavesdropping methods commonly employed on other transmission mediums. Because light travels through the glass fiber and does not emit electromagnetic signals like copper, the chances of undisturbed interception are significantly reduced. This inherent characteristic increases the security of the data being transmitted, creating a highly secure communication medium.

The other options do not specifically address the security aspect in the same way. Encrypting data packets is a security measure that could be applied to any transmission medium, not unique to fiber optics. While being less susceptible to interference enhances data integrity and quality, it does not directly contribute to the security of the data itself. Digital signaling technology is also not a security measure; it more refers to the method of data representation that can be utilized across
