Description
GYFTZA53 optical cable is designed for superior performance and durability in outdoor communication networks. Colored optical fibers are housed in a high-modulus loose tube filled with thixotropic gel, providing excellent sealing and water-blocking protection. At the core, a non-metallic strength member (FRP) offers outstanding tensile strength and structural stability without electromagnetic interference.
The loose tube and filler ropes are stranded around the central core to form a compact, circular cable structure, with the interstices filled with water-blocking gel for enhanced moisture resistance. A coated aluminum tape is longitudinally wrapped and covered with a polyethylene inner sheath, providing an additional layer of protection. The cable is further reinforced with double-sided coated steel tape armor, forming a robust, flame-retardant outer layer to ensure safety and reliability in high-risk environments.
This construction makes the GYFTZA53 cable an excellent choice for applications requiring flame resistance, moisture protection, and high mechanical performance in demanding outdoor settings.
Feature
Cross-section Diagram
- Hydrolysis-Resistant Loose Tube Material:
Constructed from high-modulus material, the loose tube offers excellent resistance to hydrolysis and high mechanical strength, ensuring long-term reliability and durability.
The loose tube is filled with thixotropic gel, providing essential sealing and water-blocking protection to safeguard the optical fibers from environmental moisture and damage.
- Flame-Retardant Sheath Material:
The outer sheath is made of a flame-retardant material, delivering superior fire resistance to meet safety requirements in high-risk environments.
- Non-Metallic Central Reinforcing Core (FRP):
The central strength member is a non-metallic FRP (Fiber Reinforced Plastic) core, offering excellent tensile strength and structural integrity without electromagnetic interference.
- Exceptional Mechanical and Temperature Performance:
Engineered to perform reliably under mechanical stress and across a wide range of temperatures, making it suitable for various outdoor environments.
- Moisture-Resistant Aluminum Tape Coating:
Longitudinally wrapped coated aluminum tape provides effective moisture resistance, enhancing the cable’s durability in wet conditions.
- Double-Sided Corrugated Steel Tape (PSP) Armor:
The cable’s armor features double-sided coated steel tape, offering enhanced protection against moisture ingress and mechanical impacts, ensuring reliability in challenging environments.
Application Scenario
- Urban Communication Networks:
Ideal for backbone and distribution networks in cities, where fire safety compliance is critical, and cables must endure urban environmental conditions.
- Industrial Zones:
Perfect for deployment in factories, refineries, and other industrial settings where potential fire hazards and mechanical stresses are common.
- Underground Duct Installations:
Suitable for underground ducts, as the water-blocking gel and aluminum tape provide excellent protection against moisture ingress.
- Tunnel and Subway Systems:
Designed for use in tunnels, subways, and confined spaces, ensuring flame retardancy and reliable communication in challenging conditions.
- Coastal and High-Humidity Areas:
Effective in regions prone to heavy rain, high humidity, or coastal environments, with robust moisture-blocking and corrosion-resistant properties.
- Aerial Deployments:
Lightweight and strong, making it ideal for aerial installations where the non-metallic core prevents electromagnetic interference.
- Critical Infrastructure Projects:
Essential for smart city projects, transportation hubs, and emergency communication networks, where safety, reliability, and high performance are prioritized.
- Remote and Rural Networks:
Suitable for long-distance communication in remote or rural areas, offering durable construction to withstand harsh weather conditions.
