Most fiber optic cable installations are designed around controlled pulling. Pushing fiber cable through a pathway can cause buckling, kinking or jacket damage, especially in longer runs. Respecting the pulling process is critical, as an improperly pulled cable can cause broken strands, increased attenuation, connector damage, microbends or macrobends, intermittent performance and ultimately failed certification testing. Even if a damaged cable appears intact on the outside. Multiple types of fiber cable from different manufacturers were tested, and all showed signs of damage when pulled with too much tension or around a bend with too small a radius. Chart 1 shows the relationship between installation load and. When deploying fiber links in data centers, LANs, or even in outside plant networks, fiber is pulled between equipment and spaces through pathways, cable managers, cable tray, risers, or conduit. Fiber cable is designed to be pulled with much greater force than copper wire if pulled correctly, but excess stress on the cable may harm the fibers, potentially causing eventual failure. In addition, the drawer structure also facilitates high-density wiring and good cable management.
