Stranded Loose Tube 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.

Key Features:‌

• ‌Durable & Reliable:‌ Excellent mechanical strength and temperature stability.

• ‌Robust Loose Tubes:‌ Made of high-strength, hydrolysis-resistant material.

• ‌Fiber Protection:‌ Special gel filling safeguards the fibers.

• ‌Crush & Bend Resistant:‌ Designed for flexibility and durability.

• ‌Waterproof Design:‌ Multiple layers ensure protection:

• Steel wire central strength member

• Loose tube filling compound

• 100% core filling

• APL moisture barrier

• PSP (Plastic Sheathed Steel) tape for extra moisture resistance

• Water-blocking materials

‌Compliance:‌
The GYTA53 cable meets the ‌YD/T 901‌ and ‌IEC 60794-1‌ standards.
