Description
GYFTA optical cable is a high-performance solution tailored for reliable and efficient communication in diverse environments. Its construction features colored optical fibers housed in a loose tube made from high-modulus material, providing excellent mechanical strength and hydrolysis resistance. The tube is filled with thixotropic gel, ensuring effective water-blocking and fiber protection.
At the core of the cable lies a glass fiber reinforced plastic (FRP) strength member, offering exceptional durability and structural integrity. The loose tube and filler ropes are stranded around the central core, forming a compact, circular cable structure. The interstices within the cable core are filled with additional thixotropic gel, creating a double-layer water-blocking system.
An aluminum tape is longitudinally coated around the cable core for added shielding, followed by a robust polyethylene sheath that enhances the cable’s durability and resistance to environmental factors.
Feature
Cross-section Diagram
- Durable Loose Tube Material: The loose tube is made of a high-modulus material with excellent resistance to hydrolysis and high mechanical strength, ensuring long-term reliability.
- Exceptional Mechanical and Temperature Performance: Designed to maintain stability under various mechanical stresses and extreme temperature conditions.
- Aramid Yarn Reinforcement: Integrated aramid elements significantly enhance the tensile strength, allowing the cable to withstand high pulling forces during installation.
- Thixotropic Gel Protection: The loose tube is filled with thixotropic gel, providing essential sealing and water-blocking protection for the optical fibers.
- UV-Resistant PE Sheath: The polyethylene outer sheath offers outstanding resistance to ultraviolet radiation, protecting the cable from environmental degradation.
- Non-metallic Central Strength Member: A single non-metallic FRP core ensures excellent structural integrity while eliminating electromagnetic interference.
Application Scenario
- High-Humidity Environments:
Ideal for areas with high humidity, such as coastal regions, rainforests, or areas with heavy rainfall. Its water-blocking gel and hydrolysis-resistant materials provide excellent waterproof performance.
- High Electromagnetic Interference (EMI) Areas:
The non-metallic central reinforcement makes it perfect for areas with strong electromagnetic interference, such as power plants or near high-voltage transmission lines.
- Aerial Cable Installations:
Enhanced tensile strength and UV-resistant outer sheath make it an excellent choice for aerial applications, capable of withstanding wind pressure and tension.
- Duct Cable Installations:
Its compact and lightweight structure allows for easy installation in narrow conduits, while its water-blocking capabilities effectively protect against underground moisture.
- Harsh Climate Conditions:
Exceptional temperature characteristics and mechanical performance ensure reliable operation in cold, high-temperature, or environments with frequent temperature fluctuations.
- Long-Distance Communication:
With outstanding optical performance and low attenuation, it is well-suited for long-distance communication links, such as intercity, rural, or remote area backbone networks.
- Seismic-Prone Regions:
The non-metallic structure enhances resilience under extreme vibrations caused by earthquakes, reducing the likelihood of damage.
- Smart Cities and Outdoor Network Infrastructure:
Suitable for backbone networks in smart city infrastructure, including traffic monitoring, smart streetlights, and public Wi-Fi networks.
