Description
The CB6313 DCFA optical cable is designed for outdoor installations where mechanical stability and water resistance are of prime concern. The fibers are positioned in high-modulus hydrolysis-resistant tubes with thixotropic gel for water-blocking.
A non-metallic FRP (Fiber Reinforced Plastic) central strength member provides tensile strength and prevents electromagnetic interference. The loose tubes and filler yarns are stranded around the core in a compact circular fashion. Water-blocking yarn and tape maintain the core water resistant, and a coated aluminum tape layer offers further environmental protection. The polyethylene outer sheath offers UV protection for long-term outdoor exposure.
Feature
Cross-section Diagram
- Hydrolysis-Resistant Loose Tubes: Long-lasting and pressure-resistant high-modulus material over time.
- All-Dry Protection System: Thixotropic gel, water-blocking yarn, and sealing tape together to ensure no water ingress.
- UV-Resistant Sheath: Protected from sun exposure by polyethylene outer sheath.
- Non-Metallic FRP Core: Mechanical strength with no electromagnetic interference, supplied by non-metallic FRP core.
- Temperature Stability: From -40℃ to +70℃, stable performance.
- Compact Stranding: Tube shrinkage reduced and structural integrity during installation maintained.
Applications
- Telecommunications Networks: Backbone networks, metropolitan area networks (MANs), and FTTH installations.
- Data Centers: Network expansions and high-density connections.
- Outdoor Installations: Aerial, duct, or direct burial appropriate.
- High-UV Areas: Withstands prolonged exposure to sunlight in outdoor installations.
- Energy and Industrial Systems: Smart grid monitoring, renewable energy plants, and EMI-sensitive installations.
Delivery
- Standard delivery length: 2000 m per reel.
- Available in custom lengths according to customer requirements.
