Armoring of fiber optic cables refers to covering the exterior of a fiber optic cable with a layer of metallic or non-metallic material to provide protection and enhance the mechanical strength and durability of the cable. Armoring prevents damage to the fiber optic cable from external forces, pressure, stretching, crushing and bending, and protects the fiber inside from physical damage.
The armoring material is usually metal, such as steel tape or steel wire. Steel tape armor is usually wrapped around the outside of the fiber optic cable to provide better strength and resistance to stretching. Steel wire armor, on the other hand, covers the fiber optic cable in a braided or spiral form to enhance the cable's ability to withstand external forces. These metallic armors not only protect the cable from external physical damage, but also provide additional protection, such as protection from rodent bite or corrosion in the external environment.
In addition, the armoring of fiber optic cables can also use non-metallic materials, such as aramid (aramid) fibers (e.g. Kevlar) or glass fibers. These materials offer certain protective and reinforcing properties, while being lightweight and flexible.
Armored fiber optic cable is an external covering used to protect the cable from external physical damage and to enhance the mechanical strength and durability of the cable. Different types of armoring materials can be selected for specific needs to ensure that the fiber optic cable has the required protection and performance properties during installation and operation.
