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.
Key Features
Robust Performance: Excellent mechanical strength and temperature stability
Durable Loose Tubes: Constructed with high-strength, hydrolysis-resistant material
Advanced Fiber Protection: Specialized filling compound ensures critical safeguarding of optical fibers
Flexible Design: Offers crush resistance and installation flexibility
Comprehensive Waterproofing: Achieved through multiple protective layers:
Single Fiber Reinforced Plastic (FRP) central strength member
Loose tube filling compound
100% core filling with water-blocking materials
APL moisture barrier
PSP enhanced moisture protection
Compliance
The GYFTA53 cable meets the requirements of YD/T 901 and IEC 60794-1 standards.
