Non Metallic Loose Tube Aerial Fiber Optic Cable With Kevlar Reinforcement
Non-Metallic Loose Tube Aerial Fiber Optic Cable With Kevlar Reinforcement
Description
The fibers are arranged within a high modulus plastic loose tube, which is then filled with a water-resistant
compound. Kevlar is incorporated within the outer jacket of this portion of the cable, which is supplemented
by wires for support. Finally, the assembly is encased in a PE sheath, forming a figure 8 structure.
Application
This specification outlines the overall criteria for a Figure 8 self-supporting Center Tube Optical cable intended
for aerial and overhead installations.
Characteristics
1 Non-metallic strength provides outstanding resistance to electromagnetic interference.
2 Demonstrated loose tube design ensures reliable performance.
3 Exhibits exceptional mechanical and environmental durability.
4 Offers excellent flexibility and bending capabilities.
5 Compact outer diameter, lightweight, and easy to install.
6 Kevlar reinforcement significantly enhances the cable's tensile strength.
