What caution should be taken when using cable ties on fiber optic cables?

When working with fiber optic cables, it is crucial to understand that applying cable ties too tightly can cause damage to the cables. Fiber optic cables contain delicate glass fibers that are sensitive to pressure. If a cable tie is fastened too tightly, it can lead to stress on the fiber, potentially resulting in micro-bends or even breaking the fiber strands inside the protective casing. This damage can significantly impact the performance of the cable, leading to signal loss or failure.

Using cable ties appropriately entails ensuring they are snug enough to hold the cables together without exerting excessive pressure. This helps maintain the integrity of the fiber optic cable and ensures optimal signal transmission. Hence, it is important to handle them with care, particularly in environments where cables might be subjected to movement or where high packing densities are involved.
