Fig. 8: 12Core Fiber, GYTC8A, SM G652D Description:

The fibers are placed in a loose tube made of high-modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire is located in the center of core as a metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular cable core. After Aluminum Polyethylene Laminate (APL) is applied around the cable core, this part of cable, along with the stranded wires as the supporting part, are completed with a polyethylene (PE) sheath to form the figure 8 structure. This kind of cable is specifically applied for self-supporting aerial installation

GYTC8A Figure 8 Outdoor Aerial Fiber Optic Cable Characteristic:

  • Good mechanical and temperature performance
  • High-strength, loose tube that is hydrolysis resistant
  • high tensile strength of stranded wires meet the requirement of self-support and reduces the installation cost
  • special tube filling compound ensure the critical protection of fiber
  • The following measures are taken to ensure the cable is watertight:
  • Steel wire used as the central strength member
  • 100% cable core filling
  • APL enhances moisture-proof
  • Water-blocking material
  • GYTC8A Figure 8: Outdoor Aerial Fiber Optic Cable Application:
  • Adopted to outdoor distribution;
  • Suitable for aerial
  • Long-distance and local area network communication.
