Description
GYTZA53 optical cable is engineered to deliver high performance and reliability in demanding outdoor environments. Colored optical fibers are securely placed in a loose tube made of high-modulus material, offering superior hydrolysis resistance and mechanical strength. The tube is filled with thixotropic gel, providing critical water-blocking and sealing protection to the optical fibers.
At the core of the cable is a metal strength member, enhancing tensile strength and ensuring structural stability. The loose tubes and filler ropes are stranded around this central strength member, forming a compact circular cable core, with the interstices filled with water-blocking gel to prevent moisture ingress.
The cable's construction includes a coated aluminum tape, longitudinally wrapped and encased in a polyethylene inner sheath for added protection. A double-sided coated steel tape armor layer provides enhanced mechanical robustness and forms a flame-retardant outer protective layer, ensuring compliance with fire safety standards.

Cross-section Diagram
- Hydrolysis-Resistant Loose Tube Material:
Constructed from high-modulus material, the loose tube provides superior resistance to hydrolysis and high mechanical strength, ensuring long-lasting protection for the optical fibers.
The loose tube is filled with thixotropic gel, offering essential sealing and water-blocking protection to shield the optical fibers from environmental moisture and damage.
- Flame-Retardant Sheath Material:
The outer sheath is made from a special flame-retardant material that meets stringent fire safety standards, ensuring reliable performance in fire-sensitive environments.
- Metal Center Strength Member:
A single metal core enhances the cable’s tensile strength and structural stability, making it suitable for installations requiring robust support.
- Outstanding Mechanical and Temperature Performance:
Designed to deliver reliable performance under mechanical stress and across a wide range of temperature conditions, ensuring adaptability to diverse environments.
- Coated Aluminum Tape Layer:
The longitudinally wrapped aluminum tape provides an effective moisture barrier, enhancing the cable’s resistance to environmental humidity and wet conditions.
- Double-Sided Corrugated Steel Tape (PSP) Armor:
The cable is further protected by double-sided coated steel tape, which enhances resistance to moisture ingress and mechanical impacts, ensuring long-term durability even in challenging outdoor conditions.
Application Scenario
- Urban Communication Networks:
Ideal for backbone and distribution networks in cities where fire safety compliance and reliable performance are crucial.
- Industrial and High-Risk Fire Areas:
Suitable for deployment in industrial zones, chemical plants, and other areas with potential fire hazards due to its flame-retardant outer sheath.
- Underground Duct Installations:
Perfect for underground ducts or tunnels where moisture resistance and robust mechanical properties are necessary to prevent cable degradation.
- Tunnel and Subway Systems:
Designed for confined spaces such as tunnels and subways, providing flame retardancy and high tensile strength for secure and safe operation.
- High-Humidity and Coastal Environments:
The water-blocking gel and aluminum tape layer make it ideal for installations in coastal areas, regions with high rainfall, or other moisture-prone settings.
The cable’s reinforced structure and excellent tensile strength make it suitable for aerial installations where mechanical stress and UV resistance are key.
- Critical Infrastructure and Smart City Projects:
Essential for reliable communication in smart city networks, transportation hubs, and public infrastructure where safety and long-term durability are priorities.
Effective for long-distance installations in remote or rural locations, providing durable and reliable performance in harsh outdoor conditions.
