Central Tube Type Lightweight Armored Fiber Ribbon Optical Cable features a hydrolysis-resistant loose tube filled with water-blocking gel for superior fiber protection. A double-sided steel tape, combined with water-blocking gel, ensures compactness and excellent moisture resistance. To enhance tensile strength and stability, two parallel steel wires are embedded on both sides of the cable.
The cable is encased in a flame-retardant sheath, offering additional protection against environmental and fire hazards. Its lightweight design and robust structure make it ideal for duct installations, aerial applications, and other demanding outdoor environments.

The loose tube material is highly resistant to hydrolysis and pressure, providing durability and protection in challenging environments.
Special grease inside the loose tube safeguards the optical fibers from environmental factors, maintaining their integrity and performance.
Precise control of fiber excess length and cable core structure ensures superior tensile performance and compliance with temperature standards.
Double-sided coated steel tape offers robust protection against moisture penetration.
Two parallel steel wires provide excellent tensile strength and maintain cable stability during installation and operation.
Small diameter and lightweight design facilitate easy handling and installation, making it suitable for long-distance deployments.
GYDXTW is an excellent choice for outdoor applications requiring lightweight, flexible, and moisture-resistant optical cables. It is particularly suited for duct and aerial installations, urban backbone networks, and areas with high humidity or fire safety requirements.
1. Duct Installations
Ideal for deployment in ducts due to its compact size, lightweight design, and flexibility, ensuring easy and efficient installation over long distances.
2. Aerial Installations
Suitable for aerial installations with proper support measures, offering excellent performance in environments exposed to wind, rain, and temperature fluctuations.
3. High-Moisture or Water-Prone Areas
Equipped with water-blocking gel and steel tape, it ensures reliable performance in regions with high humidity, heavy rainfall, or frequent water exposure.
4. Backbone Networks
Widely used in backbone communication networks, providing high-capacity and reliable fiber transmission over extended distances.
5. Urban and Suburban Communication Networks
Perfect for connecting urban and suburban areas where lightweight and durable cables are essential for efficient installation and long-term performance.
6. Low to Moderate Mechanical Stress Environments
Designed to perform well in environments with minimal to moderate mechanical stresses, such as stable terrains and regions without heavy machinery.
7. Fire-Risk Areas
The flame-retardant sheath makes it suitable for areas where fire safety standards are critical, such as near buildings or industrial facilities.
