Armored fiber optic cables are specialized cables designed to provide extra protection to the fragile optical fibers within.  These cables are commonly used in environments where there is a risk of physical damage to the cables, such as in outdoor installations, industrial settings, or areas with high foot traffic.

The typical construction of an armored fiber optic cable involves enclosing the optical fibers within a sturdy metal or polymer armor.  This armor provides resistance to crushing, bending, and abrasion, thereby safeguarding the delicate fibers from damage.  Additionally, the armor also protects the cables from rodents, moisture, and other environmental hazards.

Armored fiber optic cables come in various designs to suit different applications.  They may have different types of armor materials, such as steel, aluminum, or corrugated metal, depending on the level of protection required and the environmental conditions they will be exposed to.  Some armored cables are also designed to be rodent-resistant or to withstand extreme temperatures.

In addition to their protective properties, armored fiber optic cables also maintain the performance characteristics of standard fiber optic cables, such as high bandwidth, low signal attenuation, and immunity to electromagnetic interference.  This makes them suitable for a wide range of applications, including telecommunications, data centers, security systems, and industrial automation.

Overall, armored fiber optic cables provide a robust solution for applications where durability and reliability are paramount, ensuring the integrity of optical communication networks in challenging environments.

What is Armored Fiber Optic Cable?
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.

What is Armored Fiber Cable for Indoor and Outdoor Use?
According to different environment for installation of fiber optic cable, loose buffered armored fiber optic cable and tight buffer armored cable are use.Both loose buffered and tight buffered armored fiber optical cable can use indoor or indoor/outdoor but usually loose buffer armored fiber optic cable use in outdoor environment

What Is Indoor Armored Fiber Optic Cable?
Indoor Armored Fiber Optic Cable is used in building wiring applications. Installed in walls, between floors, in plenum air handling ducts and under data center floors indoor application usually use loose buffered and tight buffered fiber or tight buffered fiber optic cable , inner jacket & strengths members .inner jacket usually surrounded by a spirally wrapped interlock armor .indoor armored fiber optic cables are less able to withstand mechanical pressure and temperature than outdoor fiber optic cables but they can retard fire effectively by using LSZH material in jacket .Tight Buffered is flexible and easy to handle. Light-weight aluminum interlock armor is standard. This design eliminates the need for inner duct or conduit and the cost associated with the installation of either. Ideal intra-building cable solution

What is Indoor/Outdoor Armored Fiber optic cable Cable?
Indoor/Outdoor Armored Fiber optic cable allow to link network from building to building Without changing the indoor cable to outdoor cable or vise versa . it’s important that cable does not have any electrical code to pass into building and damage equipment .Indoor/Outdoor Armored Fiber optic cable Cables are designed to meet both the stringent environmental requirements typical of outside plant cable AND the flammability requirements of premise applications.The advantages to using Indoor/Outdoor Armored Fiber optic cable include fewer connection points, thus fewer points of potential failure, enhanced security and improved electrical performance since light attenuation, which occurs as the result of connectors, splices, etc., is avoided. Attenuation negatively impacts network performance. Additionally, many I/O cables are tight buffered, which allows them to accept connectors without the use of any kits.No Need for Inner Duct or Conduit to pass the cable.using Aluminum Interlock Armor.Color Coded for Easy Identification.Suitable for Intra-building Cable Solution.Flexible and Easy to Handle.Lightweight, Flexible Aramid Yarns Enhance Strength

Outdoor Armored Fiber Optic Cable

Armored cable for outdoor is made to ensure operation safety in complicated outdoor harsh 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.Double armoured version can be achieved by adding a layer of aluminium tape armour before the inner jacket.they have two main type Outdoor Double Jacket Steel Armoured Fiber Optic Cabledirect burial , Outdoor Double Jacket Steel Armoured Figure 8 Aerial Fiber Optic Cable

Aluminum Interlocking Armor
This armored plenum fiber cable is ideal for industrial and other installations requiring a metallic armor and has a greater flexibility than standard corrugated steel-armored (CST) cables. The interlocking preloaded armor may eliminate the need for conduit, reducing installation costs. The interlocking armor can be easily removed leaving an intact inner plenum rated cable for installation into plenums and air-handling spaces.

Direct Burial Fiber Optic Cable – Corrugated Steel Tape
Direct burial armor fiber optic cables are ideal for installations that require a rugged armored fiber cable to be buried directly in the ground or for installation in conduit where rodents are still able to get inside. The corrugated steel tape has excellent water blocking abilities, providing a protective barrier between the fiber cable and the elements surrounding it. With an operating temperature range of between -40°C and 85°C, you can be sure that the armored direct burial fiber cable will be well protected in harsh conditions.

The outdoor armored fiber cable uses tight buffered inner fibers, allowing the technician to perform direct field terminations with standard fiber connectors. This helps save time and money and offers a huge benefit over using a loose tube fiber cable. The inner cable utilizes a distribution series riser design, so the cable can even be run indoors if the armoring is removed. The versatility of this armored direct burial fiber cable is nearly endless!
