# Armoured Fiber Optic Cable: A Comprehensive Guide
## Introduction to Armoured Fiber Optic Cables
Armoured fiber optic cables are a specialized type of fiber optic cable designed with additional protective layers to withstand harsh environmental conditions and physical stresses. These cables combine the high-speed data transmission capabilities of traditional fiber optics with enhanced durability, making them ideal for demanding applications.
## Construction and Components
### Core Structure
At its heart, an armoured fiber optic cable contains the same basic components as standard fiber cables:
– Optical fibers (single-mode or multi-mode)
– Buffer coating
– Strength members
– Outer jacket
### Armouring Layers
What sets armoured cables apart is their additional protective layers:
– Interstitial metal tape (usually steel or aluminum)
– Corrugated steel tape
– Kevlar reinforcement
– Heavy-duty outer jacket
## Types of Armoured Fiber Optic Cables
### 1. Interlocking Armour
Features metal strips that interlock around the cable core, providing excellent crush resistance while maintaining flexibility.
### 2. Corrugated Armour
Uses a corrugated steel tape that offers superior protection against rodents and crushing forces.
