Unitube Non-Armored Cable GYFXTY is a high-performance fiber optic cable designed for outdoor installations where mechanical protection is not as critical. It features a unitube construction, which simplifies the design while ensuring reliable protection for optical fibers. Below is a detailed description of its components and features:

Core Structure:

• Optical Fiber Unit: The cable contains optical fibers, typically 200μm or 250μm, housed in a single loose tube made from high-modulus plastic. This unitube design minimizes the overall size and weight of the cable.
• Water-Resistant Filling: The loose tube is filled with a water-resistant compound to prevent moisture ingress, safeguarding the fibers against environmental exposure over time.
• Fiber Count: Available in configurations ranging from 2 to 24 fibers, the cable can be tailored to meet specific requirements for various applications.

Strengthening Elements:

• Water-Blocking Material: In addition to the water-resistant filling, the unitube is often wrapped with water-blocking material to further ensure that the cable remains watertight, protecting the optical fibers from potential moisture damage.
• Non-Metallic Strength Member: The cable does not include metallic armor but may use other non-metallic strength members, such as fiber reinforced plastic (FRP) or similar materials, to provide additional strength for handling tensile forces during installation and to prevent damage in less stressful environments.

Outer Sheath:

• Polyethylene (PE) Sheath: The cable is finished with a durable polyethylene (PE) outer sheath. The PE sheath provides excellent resistance to environmental factors such as UV radiation, chemicals, and moisture, ensuring long-lasting durability in outdoor installations.
• UV and Weather Resistance: The outer sheath is UV-resistant, making the cable ideal for prolonged outdoor use where exposure to sunlight and weather conditions is a concern.

Design Features:

1. Unitube Structure: The unitube design simplifies the cable construction, reducing weight and size while still offering sufficient protection for the fibers.
2. Water Resistance: The water-resistant filling and water-blocking materials keep the cable watertight, making it suitable for wet or damp environments.
3. Non-Armored Construction: While not armored, the cable still provides excellent protection for the fibers in less mechanically demanding environments.
4. Durable Outer Sheath: The PE sheath offers strong protection against the elements, ensuring reliable performance in outdoor settings.

Applications:

• Outdoor Fiber Networks: Suitable for outdoor fiber optic installations in areas where the cable will not be exposed to excessive mechanical stress or the risk of rodent damage.
• Telecommunication Networks: Ideal for urban and rural telecommunication installations, including last-mile and backbone fiber networks.
• Underground Installations: Well-suited for direct burial installations in areas with lower mechanical risks.

Technical Specifications:

• Fiber Count: Typically available from 2 to 24 fibers.
• Cable Diameter: Typically ranges from 6.0 mm to 10.0 mm, depending on fiber count and construction.
• Operating Temperature: -40°C to +70°C.
• Water Ingress Protection: Excellent water-blocking capability.
• Tensile Strength: Suitable for moderate tensile strength applications.

Conclusion:

Unitube Non-Armored Cable GYFXTY offers a cost-effective and lightweight solution for outdoor fiber optic installations where heavy mechanical protection is not required. Its unitube design, water-resistant filling, and durable PE sheath make it ideal for telecommunication networks in moderate environments. This cable ensures reliable and high-performance data transmission with minimal maintenance in less demanding outdoor conditions.
