What effect does bending a fiber optic cable have on signal quality?

• A. It improves the signal quality
• B. It has no effect
• C. It reduces the signal quality
• D. It enhances the transmission speed

Answer: (C)

Bending a fiber optic cable can significantly reduce the quality of the signal transmitted through it. Fiber optic cables work by having light signals confined within the core of the cable through total internal reflection. When the cable is bent, it can cause the light to escape from the core, which leads to attenuation or loss of signal strength. This bending can result from sharp turns or kinks in the cable, and even a gentle curve can introduce some signal degradation. When considering the signal quality, maintaining a straight or properly routed fiber optic cable is crucial because any bends can impair the integrity of the light signal, resulting in decreased performance and potential data loss. Therefore, the understanding of how bending affects fiber optic cables is vital for ensuring optimal data transmission and maintaining high signal quality in network applications.
