Methods for pulling fiber optic cables in cable trays

Cable manufacturers install special strength members, usually aramid yarn (DuPont Kevlar), for pulling. The below article explores the best practices and tools commonly used to pull fiber optic cable. Our News & Insights library is also a wealth of knowledge, and we offer articles that delve. Fiber optic cable is surprisingly strong, durable and pliable; however, several best practices should be followed to ensure a successful cable installation. Most fiber optic cables boast a pull strength of 100 – 200. When deploying fiber links in data centers, LANs, or even in outside plant networks, fiber is pulled between equipment and spaces through pathways, cable managers, cable tray, risers, or conduit. Outdoor cable may be direct buried, pulled or blown into conduit or innerduct, or installed aerially between poles.
