CB6333 GYHTY Loose Tube Layer Stranded Non-metallic Reinforced Core Optical Cable

Description

GYHTY optical cable is a high-performance, robust solution designed for demanding communication applications. Built with precision and reliability in mind, it features colored optical fibers housed in a loose tube constructed from high-modulus material. The tube is filled with thixotropic water-blocking gel, ensuring superior moisture resistance and long-term durability.

At the core of the cable lies a glass fiber reinforced plastic (FRP) central strength member, offering enhanced stability and mechanical strength. Surrounding this core, the loose tube and optional filling ropes are stranded in a precise helical structure to create a circular cable core, maximizing flexibility and tensile performance. The internal gaps are carefully filled with water-blocking gel to provide excellent protection against water ingress.

The cable is encased in a polyethylene inner sheath for added durability, followed by a layer of aramid yarn reinforcement to ensure exceptional tensile strength and resistance to mechanical stresses. A final polyethylene outer sheath completes the construction, delivering an additional protective barrier against environmental factors, abrasion, and UV exposure.

2. 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.

3. 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.

4. 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.

5. Harsh Climate Conditions:

Exceptional temperature characteristics and mechanical performance ensure reliable operation in cold, high-temperature, or environments with frequent temperature fluctuations.

6. 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.

7. Seismic-Prone Regions:

The non-metallic structure enhances resilience under extreme vibrations caused by earthquakes, reducing the likelihood of damage.

8. Smart Cities and Outdoor Network Infrastructure:

Suitable for backbone networks in smart city infrastructure, including traffic monitoring, smart streetlights, and public Wi-Fi networks.
