Stranded Loose Tube Non-armored Fiber Optic Cable 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.
Key Features:
Robust Performance: Excellent mechanical strength and temperature stability.
Durable Loose Tube: Made of high-strength, hydrolysis-resistant material.
Fiber Protection: Special tube-filling compound provides critical fiber safeguarding.
Stable Structure: Compact design prevents loose tube shrinkage.
Weatherproof Sheath: PE outer layer resists UV radiation.
Waterproof Design: Ensured through multiple layers:
Steel wire central strength member
Loose tube filling compound
100% cable core filling
APL or PSP moisture barrier
Compliance:
The GYTA/S cable meets the requirements of YD/T 901 and IEC 60794-1 standards.
