Description
GYTC8A optical cable features colored optical fibers housed in a loose tube made of high-modulus, hydrolysis-resistant material, filled with thixotropic water-blocking gel for optimal fiber protection. A central metal strength member provides robust structural support, around which the loose tube and filling ropes are helically twisted to form a compact, circular cable core. The cable core is longitudinally wrapped with coated aluminum tape and integrated with steel strand wires into an 8-shaped polyethylene sheath, offering excellent tensile strength for aerial installations and reliable performance in various environments.
Feature
Cross-section Diagram
- Good mechanical performance and excellent temperature stability.
- Steel strand wire serves as a self-supporting element, providing the required tensile strength for aerial installation and reducing installation costs.
- Loose tube material offers high hydrolysis resistance and exceptional pressure resistance.
- Special grease inside the tube ensures crucial protection for optical fibers.
- Double-sided coated steel tape enhances resistance to moisture penetration.
Application Scenario
1. Telecommunications Networks
- Long-distance backbone networks for reliable data transmission.
- Metropolitan area networks (MANs) for urban connectivity.
Fiber-to-the-home (FTTH) and fiber-to-the-building (FTTB) installations in residential and commercial areas.
2. Aerial Installations
- Ideal for aerial deployment due to its integrated steel strand wire for self-supporting capabilities.
- Cost-effective solution for overhead installation, reducing the need for additional support structures.
3. Rural and Remote Areas
- Suitable for extending optical networks to rural and remote locations.
- Provides robust performance in challenging outdoor environments.
4. Transportation Infrastructure
- Communication networks along railways, highways, and bridges.
- Supports intelligent transportation systems (ITS) for real-time monitoring and data exchange.
