Metallic Armored Fiber Optic Cables | Heavy-Duty Protection for Harsh Outdoor Installations

ETK Kablo’s Metallic Armored Fiber Optic Cables are engineered for maximum mechanical protection and durability in outdoor, underground, and industrial environments. Reinforced with corrugated steel tape (CST) or steel wire armor (SWA), these cables are specifically designed to resist rodent attacks, mechanical impact, and soil pressure—ensuring long-lasting, reliable data transmission even in the most challenging field conditions.

Rugged Construction for Harsh Environments

These armored fiber optic cables feature a central loose tube design filled with thixotropic gel that provides superior water blocking and long-term fiber protection. The combination of a metallic armor layer and an HDPE or PE outer sheath offers excellent resistance to UV radiation, abrasion, chemicals, and temperature extremes. Whether deployed through direct burial, duct systems, or aerial networks, the construction ensures continuous data flow without interruption or degradation.

For outdoor telecom infrastructures, energy facilities, and transport systems, these cables deliver unmatched mechanical resilience and environmental protection. The armored structure safeguards the optical fibers against crushing forces, accidental digging, and rodent damage, making it ideal for mission-critical networks in data centers, military bases, and utility corridors.

Available Fiber Types and Configurations

ETK Kablo provides a wide selection of fiber types and core counts to meet diverse network requirements:

Each configuration is optimized for low attenuation, high tensile strength, and exceptional data integrity. The armored layer ensures consistent optical performance, even when exposed to high pressure, vibration, or outdoor environmental stress.

Compliance and International Standards

All ETK Kablo metallic armored fiber optic cables comply with global standards including IEC 60794, ITU-T, and EN 50173. These certifications ensure compatibility, safety, and reliability across international telecom, industrial, and data applications. Every production batch undergoes attenuation testing, crush resistance verification, and armor adhesion inspection in ETK Kablo’s state-of-the-art laboratory.

Key Advantages

• Superior Mechanical Strength: SWA and CST layers provide impact resistance and long-term stability.
• Rodent and Crush Protection: Metallic armor acts as a physical barrier against rodents and soil pressure.
• Moisture Resistance: Gel-filled loose tubes and sealed sheathing prevent water ingress and corrosion.
• Extended Lifespan: HDPE outer sheath ensures UV, chemical, and abrasion resistance for decades of service.
• Low Signal Loss: Precision fiber geometry and optimized core alignment minimize attenuation and reflection loss.

Applications

ETK Kablo’s metallic armored fiber optic cables are suitable for a wide range of high-demand installations:

• Direct Burial Networks: Long-distance underground telecom backbones and metropolitan area networks (MANs).
• Duct Installations: Fiber routes in conduits where protection against mechanical stress is required.
• Transportation Infrastructure: Railways, highways, and tunnels exposed to vibration and impact.
• Industrial & Energy Facilities: Oil refineries, power plants, and substations requiring robust signal continuity.
