Characteristics
• Exhibits excellent mechanical properties and temperature characteristics
• The loose jacket material itself has good hydrolytic resistance and high strength
• The inner tube is filled with special grease, providing crucial protection for the optical fiber
• The specially designed tight optical cable structure effectively prevents the jacket from retracting
• The PE sheath has excellent resistance to ultraviolet radiation
• Utilizes Fiber Optic 4, 6, 8, 12-core ribbon, with flexible application
• Measures are taken to ensure the waterproof performance of the optical cable:
- A single steel wire central reinforcing core
- Filling of special waterproof compound inside the loose jacket
- Complete filling of the cable core
- Coated aluminum tape (APL) moisture-proof layer
Product Standards
The GYHTY optical cable complies with the standards of YD/T 981.3 and IEC 60794-1.
