How to tighten the steel wire in optical fiber cable
A properly installed fiber optic drop wire clamp secures the cable's strength member (often aramid yarn or a steel wire), ensuring that all tension is placed on this member, not the delicate optical fibers within. Secondly, it ensures proper bend radius. 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. It also highlights key differences from standard fiber cables and important precautions to ensure safety and performance. This technique is cr g your hands together and then relaxing them (Figure 4). Incorrect methods can lead to reduced light passing through the fibers (high attenuation), cable stretching and cosmetic irregularities in the cable, or. This is where the drop wire clamp, also known as a drop cable clamp, demonstrates its indispensable value.
