Unitube Fiber Optic Cable 2~24F FRP Strengthened For Aerial Or Duct Installation
Description
The high modulus plastic tube houses the fibers, which are filled with a water-resistant compound. This as-
sembly is then encased in a water-blocking layer and flanked by two parallel FRP components. Finally, the
cable is encased in a polyethylene (PE) sheath to complete its construction.
Application
This specification outlines the fundamental criteria for a Central Loose Tube Outdoor Cable intended for
aerial or duct installation.
Characteristics
* Excellent mechanical resilience and temperature tolerance.
* Robust loose tube design resistant to hydrolysis.
* Specific tube filling compound ensures vital fiber protection.
* Resistant to crushing yet flexible.
* FRP enhances tensile strength.
* Compact, lightweight, and easy to install.
