Non-metallic outdoor optical cable

Non-metallic outdoor optical cables are all-dielectric, UV-resistant, and designed for high tensile strength, EMI immunity, and environmental durability in aerial, duct, and direct-buried installations.

Key Models and Types

1. Non-Armored Stranded Loose Tube Cables
   • Central strength member: Fiber Reinforced Plastic (FRP)
   • Loose tube filled with water-blocking compound
   • Outer jacket: Polyethylene (PE)
   • Features: Hydrolysis-resistant, crush-resistant, flexible, and immune to electromagnetic interference
   • Applications: Aerial and duct installations, especially near electrical systems or high-lightning areas
2. Non-Metallic Armored Fiber Optic Cables (ADSS)
   • Armor: Aramid yarn or glass yarn (non-conductive)
   • Central FRP/GRP strength member with aramid yarn for tensile load
   • Loose tube: Gel-filled or dry-blocked
   • Outer jacket: UV-stabilized PE, sometimes anti-tracking for high-voltage corridors
   • Features: Lightning and EMI immunity, crush and rodent resistance, lightweight, flexible, maintenance-free
   • Applications: Direct burial, duct systems, aerial ADSS installations, high-voltage zones, substations, chemical plants
3. Non-Metallic Armored Loose Tube Cables
   • Construction: UV-stabilized PE jacket, insect-resistant layer, FRP rod-style armor
   • Features: Superior crush resistance, rodent protection, flexibility, all-dielectric (no earthing required)
   • Applications: Carrier, broadband, transport, utility, campus networks, trenched and direct-buried installations
4. GYFTY63 Anti-Rodent Non-Metallic Cables
   • Fiber: 250µm in loose tube with waterproof compound
   • Central core: FRP or metallic FRP for some variants
   • Reinforcement: Glass yarn and non-metallic strength layers
   • Sheath: Inner and outer PE, UV and moisture-resistant
   • Features: High fiber count, waterproof, rodent-resistant, mechanically robust
   • Standards: YD/T 901, IEC 60794-1

Common Specifications

• Fiber Types: Single-mode (G.652/G.657) or multi-mode
• Strength Members: FRP, aramid yarn, or glass yarn (non-metallic)
• Outer Jacket: UV-stabilized PE, sometimes with anti-tracking properties
• Water Protection: Gel-filled or dry-blocked loose tubes, water-blocking fillers
• Mechanical Properties: High tensile strength, crush resistance, flexibility, rodent protection
• Environmental Resistance: UV, temperature cycling, moisture, and chemical resistance
• Standards Compliance: IEC 60794, ITU-T G.652/G.657, EN 50173

Applications

• Aerial installations near power lines (ADSS)
• Duct and underground conduit networks
• Direct-buried deployments in urban or harsh environments
• High-voltage or high-EMI areas where metallic cables are unsafe
• FTTP (Fiber to the Premises), metro-fiber, utility, and industrial networks Non-metallic outdoor optical cables provide safe, durable, and flexible solutions for modern fiber optic networks, particularly in environments where electrical conductivity, lightning, or rodent damage are concerns. Their all-dielectric design ensures long-term reliability without grounding or corrosion monitoring.
