Fiber optic cables are a first-rate option for transmitting data, being much faster than traditional copper Ethernet lines. Fiber cable can also run for much greater distances, giving it another leg up on copper cables. However, a potential weakness of fiber is fragility. Compared to copper cables, fiber is easier to break since it contains glass. That is where armored fiber optic cables come in.

Armored fiber optic cable can do everything standard fiber can do while also carrying additional protection. Underneath the jacket, there is a metal tube protecting the delicate fibers at the core of the cable. This metal tube does not hamper performance and provides protection from heavy objects, curious rodents, and other hazards. At the same time, the metal remains flexible enough to allow the cable to bend normally.

Advantages of Armored Fiber

All the options available to normal fiber (number of fibers, PVC or plenum jackets, single-mode or multimode, etc.) are also available with armored fiber. The armor allows the cable to withstand 7x the force of conventional fiber, providing a substantially larger safety margin if a heavy object is set on the cable or falls on top of it. The protection offered by armor also increases pull tension, making fiber installations easier
