Waterproof And Crush-Resistant ADSS Fiber Optic Cable For Outdoor Use
Description
The cable design prioritizes fiber protection by encasing them within a high-modulus plastic loose tube fortified
with a waterproof compound. This arrangement ensures insulation against moisture, safeguarding the enclosed
fibers. To fortify the cable further, a layer of Kevlar is wrapped around the tube, enhancing its overall strength and
resilience. Adding to its waterproofing attributes, a water-blocking material maintains the cable's compactness
and guards against water ingress. Finally, the cable is enveloped in a polyethylene (PE) sheath, offering an
additional layer of protection and reinforcing its resistance to external environmental factors.
Application
The specification sets out the fundamental requirements for a Single Jacket All-Dielectric Self-Supporting (ADSS)
cable intended for aerial or duct installations.
Characteristics
1 Reliable Mechanical and Temperature Performance: Ensures consistent functionality across varying temp-
eratures and mechanical stress, ensuring reliability in diverse environments.
2 Hydrolysis-Resistant High-Strength Loose Tube: Utilizes a durable tube resistant to hydrolysis, ensuring
prolonged performance even in moist conditions.
3 Specialized Tube Filling Compound: Provides essential protection to enclosed fibers, enhancing their dur-
ability and performance.
4 Combined Crush Resistance and Flexibility: Balances pressure resistance with flexibility, enabling versatile
installation without compromising durability.
5 Enhanced Tensile Strength with Parallel Steel Wires: Reinforces tensile strength by employing two parallel
steel wires.
6 Compact, Lightweight Design: Engineered for easy and user-friendly installation due to its lightweight and
compact structure.
