What are the two accepted methods for pulling fiber-optic cable off the cable reel in aerial installations?

In aerial installations, the two accepted methods for pulling fiber-optic cable off the cable reel are the back-pull method and the drive-off method.

The back-pull method involves attaching a winch or pulling device to the cable and pulling it back off the reel. This technique allows for controlled tension on the fiber-optic cable, which is crucial for preventing damage during installation. It also helps maintain the integrity of the cable by ensuring that it is not twisted or kinked, which can lead to performance issues.

The drive-off method typically involves using a vehicle to drive away from the spool, which allows the cable to unspool in a controlled manner. This method is particularly useful in installations where space is constrained or where a large volume of cable needs to be deployed quickly. Both methods are designed to facilitate the proper handling of fiber-optic cables, thereby enhancing installation efficiency while minimizing risk to the cable’s structure and performance.

The other methods listed are not typically used in aerial fiber-optic installations. For instance, the manual pull method generally refers to a less structured approach that can introduce inconsistencies in cable handling. The pay-off method is more related to ground-level installations, while the crane method usually involves different types of installations or environments not
