What aspect must be considered to ensure safe use of optical fiber cables in buildings?

When it comes to ensuring the safe use of optical fiber cables in buildings, the choice emphasizing the necessity of proper fasteners for support is crucial. This is because optical fiber cables are sensitive to stress and bending. The integrity of the installation relies on using appropriate fasteners to prevent excessive tension and to avoid applying pressure that could damage the fibers. When installed correctly, with suitable hardware and support methods, the cables can function effectively without risk of breakage or signal loss.

In contrast, while proximity to electrical wiring can pose interference issues, optical fiber cables are inherently immune to electromagnetic interference due to their design. Color coding, while important for identification and organizational purposes, does not influence the safety aspect of installation. The length of cable runs is also a significant consideration for performance and signal quality, but it does not directly relate to the physical support and safety of the installation process itself. Therefore, ensuring that optical fiber cables are securely fastened is essential for maintaining their integrity and operational safety.
