Which of the following must be ensured during installation of optical fiber cables?

During the installation of optical fiber cables, ensuring that they are supported properly is crucial for several reasons. Optical fiber cables are delicate and can be damaged if they are not adequately supported throughout their run. Proper support helps prevent excessive bending, pulling, or pinching of the cables, which can lead to signal loss, attenuation, or even complete failure of the transmission capabilities.

Supporting cables properly also includes adhering to manufacturer guidelines about slack loops, tension, and attachment points, which are important for maintaining the integrity of the fiber. This also helps in facilitating future access and maintenance without risking damage to the fibers.

In contrast, touching metallic surfaces or being bundled with power cables can introduce risks such as electromagnetic interference or potential physical damage. Painting for visibility is generally not a standard requirement and can lead to other issues if the paint affects the cable’s protective sheath or introduces contaminants.
