What is the most important property of fiber optic cable?
Correct answer: D. Attenuation
- A. Noise
- B. Refraction
- C. Interference
- D. Attenuation
Explanation
In fiber optic communication, attenuation refers to the weakening or loss of signal strength as it travels through the fiber optic cable. This is caused by a number of factors, including absorption of light by the fiber material itself, scattering of light due to imperfections in the fiber, and bending of the fiber. Attenuation limits the distance that a signal can travel through a fiber optic cable before it becomes too weak to be detected accurately. Therefore, minimizing attenuation is crucial for ensuring reliable data transmission over long distances.
