By utilizing a combination of these blockage detection techniques, operators can swiftly identify and address any impediments in the conduit, ensuring the successful installation of fiber optic cables without compromising the integrity of the network infrastructure.
Cable Entanglement
Causes of cable entanglement during blowing
Fiber optic cable entanglement during the blowing process can occur due to various reasons, often leading to delays and potential damage to the cables. Some common causes of cable entanglement include:
- Excessive Tension: When the tension on the cable is too high, it can cause the cable to twist and turn, leading to entanglement with other cables in the conduit.
- Uneven Distribution: Uneven distribution of cables within the conduit can create pockets of resistance, causing cables to bunch up and entangle during the blowing process.
- Sharp Bends: Sharp bends in the conduit can force the cables to twist and loop around each other, resulting in entanglement as they are pushed through the pathway.
Techniques for untangling cables without disrupting the installation process
Untangling cables during the blowing process requires a delicate approach to avoid causing further complications. Here are some techniques that can help in untangling cables without disrupting the installation process:
- Gentle Pulling: Applying gentle and consistent pulling force on the cables can often help to straighten them out and reduce entanglement.
