I recently heard that pulling fiber cables by the aramid yarns can damage the fibers. What is the proper method for pulling premises optical fiber cables?

February 4, 2020

Aramid yarns are the strength elements of the cable and specifically used so optical fibers are not damaged during installation. They also provide the mechanism for safely pulling the cable during installation. Pulling a premises optical fiber cable via its jacket is not recommended and highly likely to cause serious damage to the optical fibers.

If a premises optical fiber cable has multiple jackets and aramid yarn layers, remove approximately 12” of each jacket to expose the aramid yarns and then knot all of the yarns together. Attach the pulling line to the yarns and pull the cable using industry standard pulling techniques.
