Armored fiber optic cables are used in direct burial exterior plant applications where a strong fiber optic cable is required and, where it is required, resistance to rodent and other animal bites. The cable has good crush resistance, which is necessary for direct landfill applications. Such as GYTA53, GYFTA53, GYFTS53, GYXTW53, Etc. For direct burial cables used in rodent-hazardous areas, usually, there is a metal armor between the two layers of bushings to prevent rodents from biting through the bushings. Another application area for armored optical cables is in data centers, where the optical cables are installed below the ground, so it is possible that the optical cables will be crushed due to the extrusion of the floor. Because the armored optical cable is conductive, it must be well grounded in an appropriate way.
The typical design structure of the armored optical cable used in outdoor applications is a typical loose tube structure, which can be directly buried in the ground. The armor is usually corrugated aluminum tape covered with a polyethylene liner. This outer bushing and armor combination protects the cable from animals and will not be damaged during direct-fill installations.
Armored fiber optic cable for indoor applications, characterized by densely buffered optical fibers or loosely buffered optical fibers, strength members and inner bushings, and is externally covered with a helically wrapped interlock Metal tape armor. This armored fiber optic cable is very strong and resistant to crushing. These cables are used in areas with very high traffic and in applications where additional protection is required during installation, which also includes protection against rodent damage.
