The Application and Types of Armored Fiber Cable

What Is Armored Fiber Cable?
Armored fiber optic cable consists of a cable surrounded by a steel or aluminum jacket which is then covered with a polyethylence jacket to protect it from moisture and abrasion. It may be run aerially, installed in ducts, or placed in underground enclosures with special protection from dirt and clay intrusion.

Armored fiber optic cable is often installed in a network for added mechanical protection. Two armored fiber cable types 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.

Types Of Armored Fiber Cable

indoor armored cable

Armored fiber cable can be divided into indoor armored fiber cable and outdoor armored fiber cable. With the fast development of fiber optic communication technology and the trend of FTTX, indoor fiber optic cables are more and more required to be installed between and inside buildings. Typical indoor armored fiber cable types include GJFJV, GJFJZY, GJFJBV, GJFJBZY, GJFDBV and GJFDBZY. Compared with outdoor use fiber cable, indoor fiber cable experiences less temperature and mechanical stress, but they have to be fire retardant, emit a low level of smoke in case of burning. And indoor armored fiber optic cable allows a small bend radius to make them be amendable to vertical installation and handle easily.

Features of Indoor Armored Fiber Cable

* Good mechanical property and environment property.
* Soft, agility, convenience for connect.
* Flexible and Easy to Handle
* Cables with Improved Attenuation Available
* Adapt to harsh environments and man-made damage.

outdoor armored fiber cable

Outdoor armored fiber cable is made to protect the optical fiber to operate safely in complicated outdoor environment. Most Outdoor Armored fiber cables are loose buffer design, with the strengthen member in the middle of the whole cable, the loose tubes surround the central strength member. Inside the loose tube there is waterproof gel filled, whole cable materials used and gels inside cable between the different components (not only inside loose tube) will help make the whole cable resist of water.

Features

* Excellent attenuation performance
* Dry water blocking for moisture protection
* Polyethylene jacket for weather and UV protection
* Breakout kits available
* Corrugated Steel Tape
* Rodent Resistant
* Waterblock gel available

Application of Armored Fiber Cable

Armored fiber cable is used in direct buried outside plant applications where a rugged cable is needed and/or for rodent resistance. Armored fiber optic cable withstands crush loads well, for example in rocky soil, often necessary for direct burial applications. Cable installed by direct burial in areas where rodents are a problem usually have metal armoring between two jackets to prevent rodent penetration. Another application for armored fiber cable is in data centers, where cables are installed under the floor and one worries about the fiber cable being crushed. Indoor armored fiber optic cables may have nonmetallic armor. Metallic armored fiber cable is conductive, so it must be grounded properly. As with other fiber optic components, there are different names or meanings used. “Armor” in some companies’ jargon denotes a twisted heavy wire rope type cable surrounding the entire poly cable sheath/jacket. Single or double armor (two opposite ply layers of the steel wire) is typically used underwater near shore and shoals. Inner metallic sheath members of aluminum and/or copper are used for strength and for buried cable locating with a tone set.

An Overview Of The Armored Fiber Cable

Share

Fiber optic cables form one of the most important parts of the networking industry today. Fiber cables are composed of one or more transparent optical fibers enclosed in a protective covering and strength members. Fiber cables are used to transmit data by the mode of light. Various types of fiber cables available are multimode duplex fiber cables, single mode simplex fiber cables, single mode duplex fiber cables, armored fiber cables and plastic optical fiber cables.

What is Armored Fiber Cable

Armored Fiber Cable, is outside the optical fiber is then wrapped in a layer of protective of “armor”, is mainly used to meet the requirements of customers rodent, moisture proof, etc. Armored cable is a power cable made up by assembling two or more electrical conductors, generally held together with an overall sheath. This electrical cable with high protective covering is used for transmission of electrical power, especially for underground wiring needs. However, these cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or may even be kept exposed. They are available as single conductor cable as well as multi-conductor cables.

Common Armored Fiber Cable

Armored fiber optic cables are often installed in a network for added mechanical protection, as they have extra reinforcing in the cable housing to prevent damage. Two types of armored fiber optic cables 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.

Armored Flame Retardant Fiber Optic Cable for Indoor/Outdoor Applications

Indoor/outdoor fiber optic cables have been pretty hot in the last several years and there are good reasons for this. For service providers, indoor/outdoor fiber cables really present big time and cost savings. This cable design can come from the outdoor environment and enter a building without the need to switch cable designs to have the flame retardance required indoors. This dual purpose cable can reduce the cost of the terminations and related labor to change cable designs.

The development of dry water blocking core technology has also helped indoor/outdoor fiber cable development. This dry core technology uses water swellable materials to block the flow of moisture in the longitudinal direction.We also provide other types of fiber optic cable,such as the waterproof cable,waterproof fiber pigtail cable can be used in harsh environment. It is mainly used in outdoor connection of the optical transmitter. Waterproof fiber pigtail is designed with a stainless steel strengthened waterproof unit and armored outdoor PE jacketed cables.
