Description
Central Tube Type Flame-retardant Optical Cable exhibits good mechanical performance and temperature characteristics. Colored optical fibers are housed in loose tubes made of high-modulus, hydrolysis-resistant material, filled with thixotropic water-blocking gel for moisture protection. A layer of double-sided coated steel tape is longitudinally wrapped around the loose tubes, with water-blocking gel applied in between to ensure compactness and complete longitudinal water resistance. Two parallel steel wires provide additional strength, and the cable is finished with a flame-retardant sheath for enhanced safety and durability.

- Excellent Mechanical and Temperature Performance
- Hydrolysis-Resistant Loose Tube Material
The loose tube material provides exceptional resistance to hydrolysis and pressure, ensuring long-term durability in harsh environments.
- Enhanced Fiber Protection
Special grease inside the loose tube offers critical safeguarding for optical fibers against moisture and mechanical stress.
The sheath material is engineered for excellent flame retardant properties, enhancing safety in fire-prone environments.
- Superior Moisture Resistance
Double-sided coated steel tape provides robust protection against moisture penetration, ensuring cable reliability in wet conditions.
- Reinforced Tensile Strength
Two parallel steel wires offer excellent tensile performance and ensure cable stability during installation and operation.
- Compact and Lightweight Design
Features a small diameter and lightweight construction, making it easy to install and ideal for long-distance deployments.
Application Scenario
The GYXTZW Central Tube Type Flame-retardant Optical Cable is an excellent choice for outdoor applications requiring flame resistance, water-blocking properties, and reliable performance in demanding conditions. It is particularly suitable for urban and rural networks, industrial areas, and installations transitioning between indoor and outdoor environments.
1. Indoor-to-Outdoor Transition Installations
Ideal for installations that transition between indoor and outdoor environments, thanks to its flame-retardant sheath meeting safety requirements for indoor use.
2. Direct Burial
The cable’s robust structure and flame-retardant properties make it suitable for direct burial, particularly in areas with fire risk or stringent safety requirements.
3. Duct Installation
Lightweight and flexible, the cable is easy to install in ducts, providing excellent protection against environmental factors.
4. High-Fire-Risk Areas
Designed for environments prone to fire hazards, such as industrial zones, refineries, or power generation plants.
5. Urban and Rural Backbone Networks
Suitable for backbone networks in urban and rural areas, delivering reliable performance over long distances.
6. High-Moisture or Water-Prone Areas
Equipped with water-blocking elements, it is suitable for deployment in regions with high humidity or frequent water exposure, such as wetlands or riverbanks.
7. Environmentally Demanding Outdoor Applications
Performs well in challenging environments with temperature variations, mechanical stress, and exposure to UV radiation.
