What are two critical factors for successfully installing fiber-optic cable?

Successfully installing fiber-optic cable relies heavily on ensuring that the cable is handled correctly throughout the installation process to prevent damage and maintain performance. The two critical factors listed—cable pulling tension and cable bend radius—are particularly important because they directly affect the integrity and functionality of the fiber-optic cables.

Cable pulling tension is crucial because excessive force can lead to microbending or macrobending of the fibers, which can cause signal loss or degradation. Understanding the manufacturer's specifications for allowable pulling tension helps installers apply the correct amount of force during installation, thereby avoiding damage.

The cable bend radius is significant as well; fiber-optic cables must not be bent beyond their specified minimum bend radius. Bending the cable too tightly can lead to permanent deformation of the fiber and result in increased attenuation and possible failure of the cable to function properly. By adhering to the recommended bend radius, installers ensure that the optical fibers maintain their performance characteristics.

Together, managing the pulling tension and respecting the bend radius are essential practices that promote successful fiber-optic installations, leading to reliable communication networks.
