Description
The GYTS optical cable is applied to outdoor use requiring water resistance, mechanical stability, and lightness. The colored optical fibers are placed in high-modulus, hydrolysis-resistant loose tubes greased with thixotropic water-blocking gel for effective fiber protection against water and stress.
For added resistance to water, the loose tubes are water-blocking material coated externally, giving great longitudinal protection. Tensile strength and structural integrity are provided by two parallel steel wires on the sides of the cable. A polyethylene (PE) sheath finishes the cable, offering rugged protection against environmental exposure.
Feature
Cross-section Diagram
- Hydrolysis-Resistant Loose Tube: Maintains mechanical strength and protects fibers from moisture over long periods.
- Thixotropic Gel Filling: Seals and protects optical fibers from moisture completely and stably.
- UV-Resistant PE Sheath: Extends service life under sunlight exposure for a long time.
- Central Steel Wire: Strengthens tensile strength and structural stability.
- Double-Sided Plastic-Coated Steel Tape (PSP): Improves moisture resistance and cable structure strength as a whole.
- Stable Mechanical and Temperature Performance: Functions well under mechanical stress and within a wide temperature range.
Application Scenario
- Duct Installations: Compact and light design allows for easy handling and cost-effective installation over long distances.
- Suburban and Rural Networks: Suitable for communication networks in moderate environmental demand regions.
- High-Moisture or Humid Areas: Provides stable performance in regions with high rainfall frequency, high humidity, or near water bodies.
- Backbone Communication Networks: Reliable for long-distance data communication in outdoor backbone lines.
- Low Mechanical Stress Areas: Applicable in stable grounds or areas with no heavy machinery influence.
- Temporary or Quick Deployment: Light, flexible construction enables quick installation for temporary networks.
- Industrial and Utility Networks: Can be used in industrial or utility settings where moisture resistance is required but not complete armor protection.
The GYTS light-armored cable offers a blend of strength, water resistance, and ease of installation to address a wide range of outdoor network applications.
