Armored fiber Cable VS. Non-Armored fiber Cable, What Are The Differences?

Armored fiber cables and non-armored fiber cables are two types of cables used in telecommunications and networking to transmit data through optical fibers. The main difference between the two lies in their construction and the level of protection they offer. Here's a breakdown of the key differences:

1. Construction:

   • Non-Armored Fiber Cable: Non-armored cables are constructed with a central core made of glass or plastic fibers surrounded by a protective coating, typically made of PVC (polyvinyl chloride) or LSZH (low smoke zero halogen) material. They do not have any additional protective layers.
   •  
   • Armored Fiber Cable: Armored cables, on the other hand, have an extra layer of protection. They feature a metal or steel armor layer surrounding the core and the protective coating. The armor is usually made of steel or aluminum, providing enhanced physical protection to the cable.
   •  

2. Physical Protection:

   • Non-Armored Fiber Cable: Non-armored cables provide minimal physical protection. While the protective coating safeguards the delicate fiber core from dust, moisture, and minor abrasions, it offers limited resistance against more severe mechanical stress, such as impact, crushing, or rodent damage.
   •  
   • Armored Fiber Cable: Armored cables are designed to offer superior physical protection. The metal or steel armor layer provides robust shielding against external threats, including heavy pressure, impact, rodent bites, and other potential hazards. This additional layer makes armored cables more durable and suitable for harsh environments or areas prone to physical damage.

3. Flexibility and Bend Radius:

   • Non-Armored Fiber Cable: Non-armored cables are generally more flexible and have a smaller bend radius compared to armored cables. They can be more easily routed and maneuvered, making them suitable for installations that require tight bends or have limited space.
   • Armored Fiber Cable: Armored cables are stiffer due to the metal or steel armor layer. This makes them less flexible and increases their minimum bend radius. It's important to handle armored cables with care during installation to avoid excessive bending or kinking, which can damage the fibers inside.
   •  

4. Cost:

   • Non-Armored Fiber Cable: Non-armored cables are generally less expensive than armored cables. They are commonly used in indoor or controlled environments where the risk of physical damage is minimal.
   • Armored Fiber Cable: Armored cables are typically more expensive due to the additional layer of protection provided by the metal or steel armor. They are commonly used in outdoor installations, industrial settings, underground deployments, or areas where there is a higher risk of damage.
   •  

In summary, the main differences between armored and non-armored fiber cables lie in their physical protection, flexibility, and cost. Non-armored cables are more flexible, less expensive, and suitable for less demanding environments, while armored cables offer superior physical protection, but are less flexible and more expensive. The choice between the two depends on the specific requirements of the installation and the level of protection needed.
