GYFTY53 Overview:

GYFTY53  fiber optic cable Single Armor Double Jackets Stranded Loose Tube FRP Strength Member Waterproof Outdoor Cable use Fiber Reinforced Plastic as central strength member to provides anti-electromagnetic interference property.

It has good mechanical properties and resist to electromagnetic interference The armor structure helps to protect the cable from rat bite and moisture proof. Double-jacket structure make cable have nice properties of moisture resistance and crush resistance. A layer of water-blocking material is applied around the cable core to prevent water ingress.

  1. Cable Type:
    • GYFTY53 is a type of fiber optic cable designed for outdoor installations. It is commonly used for long-distance links and is suitable for both aerial and duct applications.
  2. Fiber Type:
    • GYFTY53 cables can accommodate both single-mode and multimode fibers, providing flexibility to support various types of optical networks.
  3. Fiber Count:
    • These cables can contain up to 288 fibers, making them suitable for high-capacity communication networks.
  4. Strength Member:
    • GYFTY53 cables typically incorporate a strength member made of either Fiber Reinforced Plastic (FRP) or steel wire. This provides mechanical support and helps protect the fibers from external stresses.
  5. Loose Tube Material:
    • The loose tubes within GYFTY53 cables are often made of Polybutylene Terephthalate (PBT), offering excellent protection for the optical fibers against environmental factors.
  6. Filling Compound:
    • Water-blocking gel or jelly is commonly used as a filling compound within the loose tubes to prevent water ingress and ensure long-term reliability, especially in outdoor environments.
  7. Armor Type:
    • GYFTY53 cables feature a double-layer corrugated steel tape armor, enhancing their durability and resistance to external mechanical forces such as crushing or impact.
  8. Outer Sheath Material:
    • The outer sheath of GYFTY53 cables is typically made of Polyethylene (PE) or Low Smoke Zero Halogen (LSZH) material, providing additional protection against environmental hazards and fire propagation.
  9. Application:
    • These cables are designed specifically for outdoor use and are suitable for installation in aerial configurations (e.g., on poles or towers) or buried in ducts.


      • GYFTY53 cables boast a high fiber count, making them ideal for densely populated areas or long-distance communication links.
      • They offer excellent water-blocking properties, ensuring reliable performance even in humid or wet conditions.
      • Resistant to environmental factors such as temperature fluctuations, UV radiation, and chemicals, GYFTY53 cables are built to withstand harsh outdoor conditions.
      • Their durability and reliability make them a preferred choice for telecommunications and networking infrastructure projects requiring robust fiber optic connectivity.


  • Frequent lightning area and anti electric field : The subway, tunnel
  • Long-distance communication: Local trunk network & User network
  • Duct and direct buried application
  • Harsh environment
