Cable ties should not be used to secure fiber optic cables in the computer room
In most cases, standard cable ties are not the ideal choice for securing fiber optic cables due to the risks of over-tightening and fiber damage. This includes pulling tension, minimum bend radius and crush loads. Cable manufacturers install special strength members, usually aramid yarn (Dupont Kevlar), to absorb the stress of pulling the cable. Use gentler options: Hook-and-loop, low-tension, and releasable ties protect fibers. Standards matter: Follow TIA-568, BICSI, NFPA 70, and UL requirements.
