Armored fiber optic patch cable retain the features of all common types fiber optic patch cables, and they are more flexible to deploy in FTTH projects inside the buildings. The armored fiber optic cable can be made similar outer diameter with the standard patch cords. Moreover, they can be with different jacket colors and jacket types such as OFNR, which protect the fiber glass inside. But how much do you know about armored fiber optic patch cables? I’m grade to introduce you the details of it.
The Structure of an Armored Fiber Optic Cable
Armored fiber cables have extra reinforcing in the cable housing to prevent damage. In basic armored fiber cable designs, the outer sleeve provides protection against wind, solvents, and abrasion. This outer sleeve is usually made of plastic such as polyethylene.
The armored fiber optic cables mainly depend on an external protective layer. The next layer between the sleeve and the inner jacket is an armoring layer of materials that are difficult to cut, chew, or burn, such as steel tape and aluminum foil. Ripcords are usually provided directly under the armoring and the inner sleeve to aid in stripping the layer for splicing the cable to connectors or terminators.
The inner jacket is a protective and flame retardant material to support the inner fiber cable bundle. The inner fiber cable bundle includes strength members, fillers and other structures to support the fibers inside. There ia always a central strength member to support the whole fiber cable. This can be solid or stranded metallic or nonmetallic material.
The types of Armored Fiber Optic Cable
Two types of armoring exist: interlocking and corrugated. 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.
The Material of Armored Fiber Optic Cable
This armoring material prevents the fiber from being stretched during cable installation, so that it can bended naturally, it has the advantages of resist high voltage and strong pull, thus it supplies cable a good protection and safety. The armored fiber optic cable contains two kinds material, one is steel material and the other one is aluminum material.
The steel armor also called heavy armor, it has a heavy weight as if its name, but its diameter is relatively large. It can withstand a strong pull power and impact power, specially, it can operating well in the harsh environment and the laying more excellent performance. Heavy armor is wrapped in a circle of wire, generally used in the riverbed and submarine etc.
The aluminum armor also called light armor, it is wrapped in a circle of aluminum wire, its diameter is smaller than steel armor about 3mm, precise control of fiber excess length, to ensure that the cable has excellent mechanical properties and temperature, at the same time it has a good ultraviolet radiation. The aluminum armor generally used in the pipelines and overhead.
No matter which kind material of armored fiber optic cable, they are belong to outdoor fiber optic, because of its protection to fiber optic cables appearance thanks to the steel material and aluminum material.
The Benefits of Armored Fiber Optic Cable:
Moisture and chemical protection;
Waterblocking of sheath interfaces;
Ability to be located accurately;
Ability to be monitored;
Armored Flame Retardant Fiber Optic Cable for Indoor/Outdoor Applications.
Armored fiber-optic cables are often installed in a network for added mechanical protection.
The armored fiber optic patch cables can be with SC, ST, FC, LC, MU,SC/APC, ST/APC,FC/APC,LC/APC etc types of terminations. You can buy fiber optic cable at Ingellen, you will have a clear mind about the structure or material from their exellent customer service, also you will find other kinds fiber patch cables like 9/125 Fiber Patch Cable there.
