Uni-tube Light-armored Fiber Optic Cable

Outdoor Duct Cables are engineered for underground conduit installations, shielding cables from environmental factors to ensure stable, reliable optical signal transmission. Their rugged jackets and armor resist compression, impact, soil corrosion, moisture, and animal damage. Installed quickly through conduits, they minimize excavation and simplify future maintenance. Ideal for long-haul communication, metro networks, and challenging crossings (rivers, highways, railways), they connect nodes and data centers with high-speed, high-capacity links.
Outdoor Aerial Cables are designed for overhead suspension between poles or towers, ensuring durability in harsh weather. Reinforced with aramid or steel wires, they withstand wind and weight, while UV-resistant, weatherproof jackets extend lifespan. Their simple installation on existing infrastructure reduces ground disruption and maintenance costs. Widely used for intercity/regional connectivity and specialized networks (power, transport, energy), they enable real-time data transmission between nodes and devices.
Product Description
The loose tubes (along with filling ropes) are helically twisted around the central reinforcement core to create a compact, circular cable core. Any gaps within the core are filled with water-blocking materials. A plastic-coated aluminum tape (APL) is then longitudinally wrapped around the core, followed by extrusion of a polyethylene inner sheath. Next, a double-sided plastic-coated steel tape (PSP) is longitudinally applied, and finally, a polyethylene outer sheath is extruded to complete the cable assembly.
Technical Advantages
Enhanced Physical Properties: Superior mechanical robustness and temperature stability
Durable Loose Tubes: High-strength, hydrolysis-resistant material ensures longevity
Fiber Protection System: Specialized filling compound provides critical optical fiber safeguarding
Structural Resilience: Combines crush resistance with installation flexibility
Advanced Moisture Defense: PSP (Plastic Sheathed Steel) tape enhances waterproofing
Reinforced Strength: Dual parallel steel wires guarantee exceptional tensile capability
Efficient Design: Compact profile and lightweight construction enable easy handling
Extended Production Capability: Supports longer continuous manufacturing lengths
Compliance Certification
GYXS/GYXTW cable meets the specifications of YD/T 769 industry standard.
