All Dielectric Self Supporting ADSS Fiber Optic Cable
Description
The cable design incorporates high-modulus plastic tubes housing the fibers, filled with a water-resistant
compound. Adding an extra layer of protection, Kevlar wraps around this assembly. To ensure a waterproof
and compact structure, a water-blocking material separates the Kevlar yarn and the loose tube. Lastly, the
cable is encased in a durable polyethylene (PE) sheath, providing defense against external elements.
Application
This specification outlines the overall prerequisites for a Single Jacket All-Dielectric Self-Supporting (ADSS)
cable designed for aerial or duct installations.
Characteristics
1 Reliable mechanical performance across diverse temperatures.
2 Hydrolysis-resistant, high-strength loose tube for durability.
3 Specialized tube filling compound for vital fiber protection.
4 Balances crush resistance with flexibility for versatile installation.
5 Enhanced tensile strength provided by two parallel steel wires.
6 Compact, lightweight design for easy and user-friendly installation.
