Constantly troubled by installing inner-duct or conduit to secure your optical fiber link? It is no longer a problem simply by adopting armored fiber cable—with build-in metal armor inside the outer jacket, armored cable provides extra protection for fiber optic cable, without sacrificing flexibility or functionality within fiber networks. Therefore, armored fiber cable is more robust and reliable when encountered with rodent, moisture and other issues that may cause damage. The superior features make armored fiber cable a perfect fit for campus & building backbones, data centers and industrial applications.
Armored fiber optic cable retains all the features of standard patch cables, but are much stronger and tougher to withstand crush, pressure and rodents. It possesses high flexibility and durability when used in harsh environment or limited space. Armored fiber cable is made with several layers to secure the cable. The plastic outer jacket provides protection against rodent, abrasion and twist. Then we can see a light steel tube between the optic fibers and the outer jacket, which offers better protection to the fibers in the center. And the Kevlar is placed inside the outer jacket to cover the steel tube. This picture simply demonstrates the most basic structure of armored cable, and it changes accordingly to different usage occasion.
Armored fiber optic cable can be divided into two types according to the metal tube: interlock armored fiber cable and corrugated armored cable. Interlocking armor is an aluminum armor that is helically wrapped around the cable and found in indoor and indoor/outdoor cables. It offers ruggedness and superior crush resistance. Corrugated armor is a coated steel tape folded around the cable longitudinally. It is found in outdoor cables and offers extra mechanical and rodent protection. Both types of these armored fiber cables enable installation in the most hazardous areas, including environments with excessive dust, oil, gas, moisture, or even damage-causing rodents.
Armored fiber cable can be used for indoor, indoor/outdoor and outside plant (OSP) applications. According to different installation environments, tight-buffered armored cable and loose-buffered armored cable are generally adopted: loose-buffer armored fiber cables are usually applied in outdoor applications, while both loose-buffered and tight-buffered armored fiber cable can fit indoor and indoor/outdoor applications.
Armored cable used for indoor applications often consists of tight-buffered or loose-buffered optical fibers, strengths members and an inner jacket. The inner jacket is commonly surrounded by a spirally wrapped interlocking metal tap armor. As the fiber optic communication technology develops rapidly with FTTX, there is a fast growing demand for installing indoor fiber optic cables between and inside buildings. Indoor armored fiber cable experiences less temperature and mechanical stress and it can retard fire effectively.
This armored fiber optic cable shares much popularity in today’s telecommunication network, which allows links from building to building eliminating the transition from indoor cable to outside plant cable. The following picture shows the structure of commonly used multi-fiber I/O armored fiber cable.
Armored cable for outdoor is made to ensure operation safety in complicated outdoor environment, and most of them are loose buffer design: with the strengthen member in the middle of the whole cable, loose tubes surround the central strength member. Inside the loose tube there is waterproof gel filled to make the cable water resistance. The combination of the outer jacket and the armor protects the fibers from gnawing animals and damages that occur during direct burial installations.
Armored fiber optic cable caters for both rigorous environment of the outdoor but also can be routed indoors. Despite the numerous benefit armored fiber cable retains, it also yields some inconvenience to bond and ground the cable. To handle the problem that may occur during the installation, wisely perform the following steps.
Armored fiber cable presents a premium solution to secure your network by protecting fiber links, which is specified as the primary backbone due to its distinct advantages for space efficiency, lower cost of materials and installation, as well as less risk of downtime and damage. FS.COM offers a great variety of armored cable. You can opt for single-armored/double-armored, single-jacket/double jacket, gel-filled loose-tube outdoor armored fiber cable and even multi-core tight-buffer indoor armored cable.
