Fiber optic cables carry information as pulses of light along tiny glass fibers, giving them fast and reliable connections. A duplex armored cable contains two strands of fiber inside a protective metal layer. One fibre in the cable transmits data in one direction, and the other receives data from the opposite end. It provides duplex or two-way communication.
The metal Armor that is, most of the time, made of either stainless steel or aluminum, shields the cable from pressure and bends as well as moisture and rodent damage. This way, you get fiber-level speed with extra strength and reliability. In this article, you will learn how a duplex armored cable works, its advantages, and where it’s best used. Let’s get into it.
How a Duplex Armored Cable Works?
A duplex armored cable has two fiber strands running side by side with extra protection to make them strong. Here are the materials it is made of and how it works.
1. Fiber Stands
Each fiber is coated with a thin layer of plastic and is reinforced with Kevlar or aramid yarn for durability against stretching forces.
2. Metal Armor
These fiber stands are surrounded by a metal layer. This layer prevents the cable from being crushed, impacted or even chewed by rodents, but is flexible enough for the cable to bend.
3. Outer Jacket
The outer jacket guards the cable from water, dust, and environmental conditions. Weather-resistant and outdoor versions shield the cable from the sun, weather, and other environmental conditions.
Despite all these layers, cable still transfers data at a very high speed, often 10 Gbps or more. The Metal Armor layer does not slow down the connection; it just keeps delicate fibers safe. These days, there are many installations where armored fiber is connected directly, which increases the space efficiency and ease of installation.
In short, the duplex armored cable is no different from other fiber cables, but it is more reliable because it keeps your network running smoothly.
Advantages of Duplex Armored Cable
Here are the advantages of Duplex Armored Cable.
- Strong Physical Protection
The key aspect that makes a duplex armored cable an armored cable is its metal armor. It has stronger resistance to pulling, stepping, or crushing than a normal fiber optic cable and resists damage from rodent biting, cutting, humidity, and chemical attacks.
- High Performance
Despite the added protection, these cables feature high-quality single-mode or multi-mode fibers. They work well even on high-speed networks such as 10 Gigabit Ethernet. The protective coating does not impair the performance of your internet connection.
- Durability and Longevity
The cable is known for its durability due to the combination of metal armor and Kevlar fibers. Not only can the cable resist daily wear and tear but the metals also protect the cable from being damaged even in the toughest of conditions.
- Easy to Install
Duplex armored cables are so easy to install because they have armor layers. So they don’t need any installation support or extra conduit.
Such cables can be routed through walls, ceilings, or even direct burial environments.
Typical Uses of Duplex Armored Cable
Here are typical Uses of Duplex Armored Cable.
（1）Data Centres
- Applied as patch or backbone cables connecting servers, switches and routers across racks and floors.
- Best used in raised floor environments or overhead tray cables prone to being walked upon or pinched.
- It supports high-speed interfaces such as 10GbE and 40GbE and is resistant to damage from equipment and maintenance.
（2）Commercial and office networks
- Runs between floors or through crowded cable trays for horizontal LAN and vertical backbone connections.
- It is recommended that IT rooms use armored duplex patch cords with either SC or LC connectors.
- Protects from frequent plugging/unplugging, pests, and fire sprinklers.
（3）Home and Small Business Installations
- Useful for fiber runs from outdoor drops into homes or between floors.
- Helps protect against nails, drills, rodents, and other potential sources of damage.
- Ensure reliability for smart homes, home studios, security systems, or fiber-to-the-home setups.
Conclusion
Duplex Armored Cable is simply a two-fibre strand surrounded by a strong metal armor layer. It offers reliable, high-performance fiber connectivity with added physical protection
So, it is a smart solution for data centers, home networks, and offices. If you are looking for high-quality duplex armored cables, you must visit OMC.
