Aramid Yarn Fiber Optic Cable: A Robust Solution for Modern Communication Networks
The aramid yarn fiber optic cable is a highly reliable and versatile solution for modern communication networks. Utilizing aramid yarn or Kevlar as the strength member, this cable offers exceptional tensile strength, durability, and non-conductivity, making it ideal for aerial installations, FTTH networks, and indoor applications.
Description
This aramid yarn fiber optic cable is designed with evenly distributed aramid yarn around the optical loose tube or inner sheath. It is also utilized in non-metallic fiber cables and indoor fiber cables. The cable leverages the unique properties of aramid yarn, including low density, high tensile modulus, high breaking strength, and resistance to extreme temperatures, corrosion, and chemicals.
Applications
- FTTH optical networks
- Aerial self-supporting constructions
- Indoor fiber optic installations
Features
- FRP central strength member: Provides robustness while maintaining a non-metallic structure.
- Water-blocking material inside the cable ensures protection against moisture ingress.
- Loose tube with fiber jelly compound protects the fibers from external factors.
- Rip cord facilitates easy stripping and construction.
- Outer sheath materials (PE, MDPE, HDPE) offer excellent environmental and mechanical performance.
- Standard spans of 80 meters and 120 meters, with customization available for specific needs.
