Figure-8 Self-Supporting Fiber Optic Cable | Factory Supply

GYTC8A Figure-8 Stranded Loose Tube Self-Supporting Non-armored Cable

Integrated Aerial Solution for Seamless Long-Distance Connectivity

The GYTC8A Figure-8 Cable is a specialized outdoor fiber optic cable designed for high-efficiency aerial installations. Its distinctive “figure-8” cross-section integrates a robust steel messenger member directly into the cable structure, allowing for single-pass installation without the need for a separate support strand. This design significantly reduces labor time and hardware costs while ensuring exceptional stability for long-haul and inter-office communication networks.

Key Product Features

• Integrated Figure-8 Design: The cable core and a steel messenger wire are sheathed together in a figure-8 shape, enabling self-supporting aerial deployment.
• Robust Moisture Barrier: An aluminum polyethylene tape is applied around the cable core, providing a superior moisture barrier to ensure long-term signal integrity.
• Advanced Water-Blocking: Loose tubes are filled with a water-resistant filling compound, and the cable core is packed with cable jelly to prevent longitudinal water ingress.
• Metallic Strength Member: A central steel wire serves as the strength member, providing the necessary rigidity and tensile support for the circular cable core.
• Durable PE Outer Sheath: Encased in a high-density Polyethylene (PE) jacket that offers excellent UV protection and durability against environmental stressors.
