Which type of installation requires caution to prevent damage to optical fiber cables?

Surface-mounted installations require caution to prevent damage to optical fiber cables because these cables can be more exposed to physical damage in environments where they are not protected by conduits or other shielding. In surface-mounted systems, the cables often run along walls or other surfaces, making them susceptible to impacts from equipment, people, or other objects in the space. Proper cable management practices, such as using protective raceways and securing cables to minimize movement, are essential to prevent wear and tear, which can lead to signal degradation or complete failure of the optical fiber.

While other installation types also require attention to the care of optical fiber cables, the nature of surface-mounted installations places them in direct contact with the surrounding environment, making them the most vulnerable to damage. Proper installation techniques can help ensure that such cables are not subjected to excessive stress, bending, or crushing forces, which can adversely affect their performance.
