Description
Loose Tube Layer Stranded Light-armored Optical Cable is a high-performance solution designed for outdoor applications requiring reliable water resistance, mechanical stability, and lightweight construction. Colored optical fibers are securely housed in a loose tube made of high-modulus, hydrolysis-resistant material, which is filled with thixotropic water-blocking gel for superior fiber protection.
To enhance water resistance, the loose tube is externally coated with water-blocking material, ensuring robust longitudinal water-blocking performance. Two parallel steel wires are positioned on both sides to provide tensile strength and structural stability. The cable is finished with a polyethylene sheath, offering excellent protection against environmental factors.
Feature
Cross-section Diagram
- Hydrolysis-Resistant and High-Strength Loose Tube Material
The loose tube material is engineered for excellent hydrolysis resistance and high mechanical strength.
The loose tube is filled with thixotropic gel, providing critical sealing and moisture protection for the optical fibers, enhancing their reliability.
The polyethylene sheath offers superior protection against ultraviolet radiation, extending the cable’s service life in outdoor applications.
- Central Steel Wire Strength Member
A single steel wire in the center enhances the cable’s tensile strength and ensures structural stability and parallelism.
- Robust Mechanical and Temperature Performance
Designed to perform reliably under mechanical stresses and a wide range of temperatures, ensuring consistent operation in diverse conditions.
- Double-Sided Plastic-Coated Steel Tape (PSP)
The PSP layer improves moisture resistance and strengthens the cable's structure. Its corrugated design bonds effectively with the PE sheath, enhancing overall robustness and durability.
Application Scenario
GYTS Loose Tube Layer Stranded Light-armored Optical Cable is an excellent choice for duct installations, humid environments, and suburban or rural communication networks. Its lightweight, water-resistant design makes it suitable for a wide range of outdoor applications with moderate environmental demands.
1. Duct Installations
Ideal for deployment in ducts due to its compact size and lightweight design, ensuring easy handling and efficient installation over long distances.
2. Suburban and Rural Communication Networks
Suitable for communication networks in suburban and rural areas where a non-armored, cost-effective solution is sufficient.
3. High-Moisture or Humid Environments
The water-blocking gel and external water-blocking material ensure reliable performance in regions with high humidity, frequent rainfall, or near water bodies.
4. Outdoor Backbone Networks
Perfect for use in backbone communication networks, delivering reliable performance for long-distance data transmission.
5. Areas with Low Mechanical Stress
Suitable for installations in stable terrains or areas where mechanical stress is minimal, such as residential or commercial developments without heavy machinery.
6. Temporary or Rapid Deployment Scenarios
The lightweight and flexible design make it an excellent choice for temporary or rapidly deployed outdoor communication networks.
7. Industrial and Utility Communication Systems
Can be used in industrial or utility settings for network extensions that do not require armored protection but demand good moisture resistance.
