Armored Composite Optical Cable

Armored composite optical cables combine fiber optic data transmission with protective armor and optional power delivery, offering high durability and simplified network installation.

Overview

Armored composite optical cables are designed to protect delicate optical fibers while providing robust mechanical strength and, in some cases, integrated power delivery. The armor layer, typically made of stainless steel, aluminum, or Kevlar, shields the fibers from crushing, bending, rodent damage, and environmental stress, making them ideal for harsh indoor and outdoor environments. Composite or hybrid versions, such as Corning's ActiFi cable, integrate copper conductors alongside optical fibers, allowing simultaneous data and power transmission to devices like security cameras, Wi-Fi access points, or small cell networks.

Structure

A typical armored composite optical cable consists of: Outer Jacket: Polyethylene (PE) or PVC for weather and abrasion resistance. Armor Layer: Stainless steel or aluminum tubing providing mechanical protection. Strength Members: Kevlar or fiberglass rods to enhance tensile strength and prevent stretching.

Fiber Core: Single-mode or multi-mode optical fibers with buffer coatings for additional protection. Optional Copper Conductors: For hybrid cables, enabling low-voltage or bulk power delivery alongside data.

Connection and Installation

Connecting armored composite cables requires attention to both mechanical and optical integrity: Cable Preparation: Strip the outer jacket and armor carefully without damaging the fiber or copper conductors. Use specialized tools for armored cables due to their stiffness and protective layers. Connector Compatibility: Ensure connectors (LC, SC, MPO, or hybrid keystone adapters) match the fiber type and polarity.

Hybrid cables may require adapters that handle both fiber and power connections. Routing Considerations: Maintain minimum bend radii, avoid sharp edges, and ensure conduits or trays can accommodate the heavier, stiffer armored cable. Termination: Use fusion splicing or pre-terminated connectors for optical fibers.

For hybrid cables, connect copper conductors to compatible power terminals or edge devices. Testing: Verify optical performance with an OTDR or power meter and check electrical continuity for copper conductors to ensure reliable data and power delivery.

Advantages

Durability: Resistant to crushing, bending, moisture, and rodents. Simplified Infrastructure: Combines data and power in a single cable, reducing conduit congestion and installation time.

High-

Speed Support: Suitable for 10G and higher data rates, ideal for data centers, campus networks, and outdoor deployments. Flexible Deployment: Can be used in direct burial, indoor/outdoor, or industrial environments without additional conduit protection.
