What must you ensure is secure before pulling fiber optic cable?

Before pulling fiber optic cable, it is crucial to ensure that the cable reel is secure. This is important for several reasons. A secure cable reel prevents the fiber optic cable from becoming tangled or damaged during the pulling process. If the reel is not secured properly, it could roll or tip over, which may lead to the cable unwinding in an uncontrolled manner, potentially causing kinks, breaks, or other damage to the sensitive fibers inside the cable.

Moreover, a securely anchored reel allows for a smoother pulling operation, reducing the risk of excess stress being placed on the cable itself, which is vital since fiber optic cables are much more fragile compared to other types of electrical cables. Maintaining proper tension and alignment during installation helps ensure the integrity and performance of the fiber optic system once installed.

Other options, while they are parts of the cable, do not play as critical a role in the immediate logistics of pulling the cable itself.
