Question: 1 / 400

What does the protective cover on the outside of the cladding do in fiber cables?

Enhances transmission speed

Protects against physical damage

The protective cover on the outside of fiber cables plays a crucial role in safeguarding the delicate fibers within. Its primary function is to protect against physical damage caused by environmental factors, such as impacts, abrasions, and exposure to moisture or chemicals. This protective layer ensures the integrity of the fiber by preventing breakage and maintaining the optical performance of the cable.

While the other options suggest benefits such as speed enhancement, light quality improvement, and interference reduction, these aspects are typically addressed by other components of the fiber cable or through the design of the fiber itself rather than through the external protective cover. The protective cover serves as a first line of defense, ensuring longevity and reliable performance of the fiber optic system by shielding it from external threats.
