What issue can arise from the improper use of nylon tie wraps on fiber-optic cables?

The selection of microbends as the correct answer highlights a critical concern with the installation and handling of fiber-optic cables. Microbends are small, localized bends in the fiber that can occur when excessive pressure is applied, such as when nylon tie wraps are used improperly. These bends can distort the light signal traveling through the fiber, leading to signal attenuation or loss, which directly affects the performance and reliability of the fiber-optic network.

Using tie wraps that are too tight or applying them in a way that pinches or puts pressure on the cable can cause microbending, which can create significant issues over time. Maintaining proper handling and securing methods for fiber-optic cables is essential to ensure signal integrity and overall system performance. Understanding how these factors interplay is vital in the installation and maintenance of fiber-optic networks.
