# Armored Fiber Cable: A Comprehensive Guide to Its Features and Applications

## Introduction to Armored Fiber Cable

Armored fiber cable is a specialized type of fiber optic cable designed with additional protective layers to enhance durability and resistance to environmental factors. Unlike standard fiber optic cables, armored variants incorporate metal or non-metallic armor beneath the outer jacket, providing superior protection against physical damage, moisture, and rodent attacks.

## Key Features of Armored Fiber Cable

### 1. Enhanced Protection

The most distinctive feature of armored fiber cable is its protective armor layer. This layer typically consists of:

– Interlocking metal armor (usually aluminum or steel)
– Corrugated steel tape
– Non-metallic armor (for environments requiring non-conductive materials)

### 2. Durability

Armored fiber cables are built to withstand:

– Crushing forces
– Impact damage
– Rodent bites
– Extreme temperatures

### 3. Environmental Resistance

These cables offer excellent protection against:

– Moisture and water ingress
– Chemical exposure
– UV radiation (when properly jacketed)

## Types of Armored Fiber Cable

### 1. Indoor Armored Cable

Designed for use inside buildings with:

– Lighter armor construction
– Flame-retardant jackets
– LSZH (Low Smoke Zero Halogen) materials for safety

### 2. Outdoor Armored Cable

Built for harsh outdoor environments featuring:

– Heavy-duty armor
– Water-blocking materials
– UV-resistant jackets

### 3. Direct Burial Armored Cable

Specifically designed for underground installation with:

– Extra-thick armor
– Moisture-resistant gel filling
– Rodent-resistant construction

## Applications of Armored Fiber Cable

### 1. Industrial Environments

Armored fiber cables are ideal for:

– Manufacturing plants
– Oil and gas facilities
– Mining operations
– Power plants

### 2. Harsh Outdoor Installations

Commonly used in:

– Underground conduits
– Aerial installations
– Coastal areas with high salt content
– Extreme temperature zones

### 3. High-Security Locations

Preferred for:

– Military installations
– Government facilities
– Data centers requiring extra protection

### 4. Transportation Infrastructure

Widely deployed in:

– Railway systems
– Highway communication networks
– Airport communication backbones

## Installation Considerations

When working with armored fiber cable, consider these important factors:

### 1. Bending Radius

Maintain proper bending radius to prevent damage to fibers:

– Typically 10-15 times the cable diameter
– More critical than with standard fiber cables

### 2. Grounding Requirements

For metallic armored cables:

– Proper grounding is essential
– Prevents electrical hazards
– Reduces electromagnetic interference

### 3. Termination Methods

Special techniques may be required:

– Armor transition kits
– Specialized connectors
– Proper strain relief

## Advantages Over Standard Fiber Cables

Armored fiber cables offer several benefits:

– Longer lifespan in harsh environments
– Reduced maintenance costs
– Lower risk of service interruptions
– Greater flexibility in installation locations

## Conclusion

Armored fiber cable provides a robust solution for demanding networking environments where standard fiber optic cables might fail. With its enhanced protection, durability, and versatility, it has become an essential component in industrial, outdoor, and high-security applications. When selecting armored fiber cable, carefully consider your specific environmental conditions and installation requirements to choose the most appropriate type for your needs.
