Which of the following is an advantage of fiber optics that makes it ideal for secure data transmission?

Fiber optics are known for their superior security features compared to other forms of data transmission. This is primarily because fiber optic cables transmit data as light signals through glass or plastic fibers, making it extremely difficult to tap into the signaling without detection. Unlike copper cables, where signals can be intercepted through electromagnetic interference, fiber optics do not emit electromagnetic signals that can be easily accessed by unauthorized parties.

Additionally, any attempt to physically cut or tap into a fiber optic cable typically results in a noticeable disruption in service, which provides an added layer of security. This inherent property of optical fibers to confine light within their core, along with the lack of external electromagnetic radiation, makes fiber optics particularly suitable for secure data transmissions in applications that require confidentiality and protection against eavesdropping.

While size, high speed, and low attenuation are notable advantages of fiber optics, they do not inherently provide the same level of security that fiber optics deliver during data transmission. Therefore, security stands out as the defining characteristic that makes fiber optics an ideal choice for secure communications.
