1. Overview
GYTC8S Figure‑8 fiber optic cable is a self-supporting aerial cable solution specifically designed for outdoor environments. With a distinctive figure‑8 profile formed by bonding a steel messenger wire and an optical fiber core, this cable eliminates the need for external suspension hardware during installation.
Jiqian Fiber Optic Cable, as a dedicated manufacturer and technology-driven company, specializes in the research, development, and production of GYTC8S cables. We offer reliable, high-performance solutions tailored to the demanding needs of modern fiber-optic networks.
2. Structural Features
- Fiber Core in Loose Tube: Optical fibers are housed within loose tubes made from high-strength PBT. These tubes are filled with water-blocking gel to provide long-term stability and protect against moisture.
- Water-Blocking Elements: The cable incorporates water-swellable yarn and tape for enhanced waterproofing and environmental resilience.
- Corrugated Steel Tape Armor: A layer of PSP (polyethylene-coated steel tape) shields the internal fibers from crushing forces and mechanical stress.
- Steel Messenger Wire: A galvanized stranded steel wire is pre-attached in the figure‑8 structure, enabling self-supporting aerial deployment.
- PE Outer Sheath: The outer jacket is made of UV-resistant polyethylene, ensuring long-term outdoor durability.
3. Key Technical Parameters
- Fiber Count: 2 to 144 cores (higher counts available upon request).
- Cable Diameter: Approx. 9–12 mm.
- Tensile Strength: Up to 3000 N (short-term); >1000 N (long-term).
- Crush Resistance: Typically 1000–2000 N/100 mm.
- Bend Radius: ≥15x cable diameter (static); ≥20x diameter (dynamic).
- Temperature Range: –40 °C to +70 °C.
- Attenuation: ≤0.36 dB/km at 1310 nm; ≤0.22 dB/km at 1550 nm.
As part of our quality assurance process, Jiqian Fiber Optic Cable rigorously tests each production batch to ensure compliance with both IEC and ITU-T standards.
4. Advantages of GYTC8S Cable
- Self-Supporting Design: The integrated messenger wire supports direct aerial installation without the need for additional support structures.
- Excellent Waterproofing: Multi-layer water-blocking components prevent water ingress and extend cable lifespan.
- Durable Outer Protection: PE jacket and armored steel tape provide outstanding protection against UV, rodents, and mechanical damage.
- Cost-Effective Deployment: Ideal for long-span aerial routes, minimizing installation labor and materials.
- Custom Options from Jiqian: We support a range of configurations—fiber type, core count, jacket thickness, and steel wire strength—to meet your project’s specific needs.
5. Applications
