Armored Fiber Optic Cable: A Comprehensive Guide

# Armored Fiber Optic Cable: A Comprehensive Guide

## Introduction to Armored Fiber Optic Cable

Armored fiber optic 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 to safeguard the delicate glass fibers inside.

This comprehensive guide will explore the various aspects of armored fiber optic cables, including their construction, types, applications, and advantages over traditional fiber optic solutions.

## Construction of Armored Fiber Optic Cable

The typical construction of an armored fiber optic cable includes several key components:

Core Components

The central part of the cable contains the optical fibers, which are extremely thin strands of glass or plastic that transmit light signals. These fibers are typically surrounded by a buffer coating for additional protection.

Armor Layer

The defining feature of armored cables is the protective armor layer, which can be made of:

  • Corrugated steel
  • Stainless steel
  • Aluminum
  • Non-metallic materials (for environments requiring non-conductive solutions)

Outer Jacket

The outermost layer provides additional protection against moisture, chemicals, and UV radiation. Common jacket materials include polyethylene, PVC, or LSZH (Low Smoke Zero Halogen) compounds.

## Types of Armored Fiber Optic Cables

Armored fiber optic cables come in several varieties to suit different applications:

Indoor vs. Outdoor Armored Cables

Indoor armored cables are designed for use within buildings and typically have lighter armor. Outdoor versions feature more robust protection against environmental factors like moisture and temperature fluctuations.

Direct Burial Armored Cables

These cables have extra-heavy armor and waterproofing for installation underground without additional conduit protection.

Aerial Armored Cables

Designed for overhead installation, these cables include strength members to support their weight and resist wind loads.

## Advantages of Armored Fiber Optic Cable

Armored fiber optic cables offer numerous benefits over standard fiber optic cables:

Enhanced Protection

The armor provides excellent resistance against:

  • Crushing forces
  • Rodent damage
  • Accidental impacts
  • Construction hazards

Longer Lifespan

The additional protection significantly extends the cable’s operational life, especially in harsh environments.

Reduced Installation Costs

In many cases, armored cables can be installed without additional protective conduits, saving on material and labor costs.

Versatility

Suitable for a wide range of applications from industrial settings to military communications.

## Applications of Armored Fiber Optic Cable

Armored fiber optic cables find use in numerous demanding environments:

Industrial Applications

Factories, oil refineries, and manufacturing plants where cables may be exposed to mechanical stress.

Military and Defense

Secure communications systems requiring rugged, tamper-resistant cabling.

Outdoor Installations

Telecommunications networks, especially in areas prone to rodent activity or construction work.

Harsh Environments

Mining operations, underwater applications, and extreme temperature locations.

## Installation Considerations

Proper installation is crucial for maximizing the benefits of armored fiber optic cable:
