Stranded Loose Tube Non-metallic Strength Member Armored Fiber Optic Cable

The Stranded Loose Tube Non-metallic Strength Member Armored Fiber Optic Cable—supplied by Orientalfiber—is an outdoor optical cable featuring a multi-layered protective structure. Its core design involves housing 250μm optical fibers within loose tubes made of high-modulus material, with the tubes filled with a water-blocking compound to prevent moisture ingress.

Key Features and Core Advantages

• Electromagnetic Interference (EMI) Immunity: By utilizing a non-metallic FRP strength member, the Stranded Loose Tube Non-metallic Strength Member Armored Fiber Optic Cable is immune to lightning strikes and electrical interference, making it suitable for high-voltage environments.
• Dual-Layer Armor Protection: The combination of APL and PSP provides superior crush resistance and high-level protection against rodent attacks and mechanical impact during installation.
• Hydrolysis Resistant Design: The high-strength loose tube material is specifically formulated to resist hydrolysis, ensuring the longevity of the fibers in humid climates.
• Comprehensive Water Blocking: A multi-tier system including tube filling compound, 100% cable core filling, and water-blocking materials ensures the cable remains watertight under hydrostatic pressure.

Technical Specifications

• Fiber Count: Customizable configurations from 2 to 144 cores.
• Strength Member: Central Fiber Reinforced Plastic (FRP) with optional PE coating for specific diameters.
• Armor Layers: Longitudinally wrapped APL (Aluminum Polyethylene Laminate) and PSP (Plastic-coated Steel Tape).
• Standard Compliance: Fully complies with YD/T 901 and IEC 60794-1 international standards.
• Environmental Range: Stable operation within a temperature gradient of -40°C to +70°C.
• Sheath Material: UV-resistant Polyethylene (PE) for extended outdoor service life.

Diverse Application Fields

The Stranded Loose Tube Non-metallic Strength Member Armored Fiber Optic Cable is deployed across various critical sectors:

1. Telecommunications Operators: Reliable backbone and access network cabling for voice and data services.
2. Power and Utility Grids: Safe data transmission in proximity to high-voltage power lines where metallic members are restricted.
3. Radio and Television: Stable signal distribution for communication and information transmission systems.
4. Transportation Infrastructure: Real-time data monitoring and communication for rail transit, highways, and smart traffic systems.

Frequently Asked Questions (FAQ)

Q: What makes the "Non-metallic" feature important for this armored cable?

A: Even though the cable has metal armor (APL/PSP), the non-metallic FRP central strength member prevents the cable from acting as a continuous conductor for lightning or high-voltage induction, significantly increasing safety in electrical corridors.

Q: Is the Stranded Loose Tube Non-metallic Strength Member Armored Fiber Optic Cable suitable for direct burial?

A: Yes. The double-armored structure (Aluminum and Steel tapes) provides the necessary tensile strength and crush resistance required for direct burial in most soil types.

Q: How does Orientalfiber ensure the cable's moisture resistance over time?

A: We utilize a 100% core filling compound combined with both APL and PSP barriers. This redundant system ensures that even if the outer sheath is damaged, moisture cannot penetrate the fiber-carrying tubes.
