When installing fiber optic cables, what is considered best practice regarding tie-wrapping?

Avoiding tie-wrapping is considered best practice when it comes to installing fiber optic cables because tight tie-wraps can lead to stress on the fibers. Fiber optic cables are sensitive to bending and tension; excessive tightness can cause micro-bending or macrobending, which can result in higher insertion losses or even breakage of the fibers.

In many installations, it is advised to only secure cables lightly or use proper securing methods that do not apply pressure directly on the cables. This allows the fibers to remain protected and maintain their integrity while still being securely fastened. Thus, the recommendation to avoid tie-wrapping helps ensure that the cables perform optimally over their operational lifespan.
