Why are Velcro straps preferred over standard plastic tie wraps when bundling pigtails for storage in a splice panel?

Velcro straps are preferred for bundling pigtails in a splice panel primarily because they do not strain the optical fibers. The flexibility and adjustability of Velcro straps allow for a secure yet gentle hold on the fibers, which is crucial to prevent any bending or tension that could lead to signal loss or damage. This characteristic is particularly important in maintaining the integrity and performance of optical fibers, as they can be highly sensitive to pressure and stress.

In contrast, standard plastic tie wraps can create tight, unyielding loops that may compress the fibers too much or inappropriately bend them, leading to potential problems. Velcro provides the advantage of being easily adjustable, allowing for changes in how tightly the pigtails are bundled without risking damage to the delicate fibers. Thus, the use of Velcro straps enhances both safety and durability in fiber optic installations.
