| Place of Origin | China |
| Brand Name | Fiberplan |
| Certification | ISO 9001; TÜV certificate |
| Model Number | GYXTC8Y |
Self Sopporting Figure 8 Optical Cable GYXTC8Y With Aramid Yarn
Description
The fibers are housed within a loose tube crafted from high modulus plastic, filled with a water-resistant
compound. Additionally, Kevlar is incorporated inside the outer jacket. This cable section, accompanied by
wires serving as supporting elements, is finalized with a PE sheath to create a figure 8 structure.
Application
This specification outlines the fundamental criteria for a Figure 8 self-supporting Center Tube Optical cable
designed for aerial installations, particularly for overhead use.
Characteristics
1 Non-metallic strength provides exceptional anti-electromagnetic capabilities.
2 Demonstrated loose tube design ensures reliable performance.
3 Outstanding mechanical and environmental resilience.
4 Superior flexibility and bending capabilities.
5 Compact outer diameter, lightweight, and easy installation.
6 Kevlar reinforcement significantly boosts the cable's tensile strength.
