Armored fiber optic cable is a type of fiber optic cable with an additional protective layer, usually made of metal or a sturdy polymer. The armor provides mechanical protection from physical damages such as crushing, abrasion, or bites from vermin. These types of cables are used for outdoor and industrial purposes where the cable is subjected to harsh environments. For example, at a construction site, and network devices in different buildings can be connected using armored cables. Or in a factory, it can be utilized for guiding fiber optic cables through regions with rigorous machinery that pose threat to the cable and robust communications using fiber optics in strained environments
