How should optical fiber cables that are installed exposed on ceilings and sidewalls be supported?

Supporting optical fiber cables installed exposed on ceilings and sidewalls by the building structure is essential for maintaining the integrity and performance of the cables. This method ensures that the fiber optic cables are securely held in place, mitigating potential damage from environmental factors or accidental contact. The building structure provides a stable and secure anchor point for the cable installation, which is crucial since fiber optics are sensitive to bending and stress.

In contrast, using electrical conduits may not provide the necessary support specifically designed for sensitive optical fiber cables. Non-conductive ties, while useful for bundling or organizing cables, do not offer the same level of stability and support as affixing them directly to the structure. Lastly, plastic brackets could theoretically provide some support, but they must be designed specifically for fiber optic applications and securely attached to the building structure to ensure proper support over time. Thus, utilizing the building structure is the most effective and reliable method for supporting exposed optical fiber cables.
