IU-ODN-CAB-FIG8-048-4KM - Iuron FIG8 Figure 8 G.652.D GYFTC8Y Unarmored Fiber Optic Cable 048 Core 4 KM

The IU-ODN-CAB-FIG8-048-4KM is a high-performance, unarmored fiber optic cable designed for various optical network applications. This cable features robust construction with water-resistant filling compounds and a non-metallic central strength member, ensuring reliable performance in self-supporting aerial installations.

The fibers, either of single-mode or multimode type, are placed in a loose tube made of high modulus plastic. The tubes inside are filled with a water-resistant filling compound. A center member locates in the center of core as a non- metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular cable core. Water blocking yarn and water blocking tape to protect cable from water. This part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE) sheath to be figure 8 structure. This kind of cable is specifically applied for self-supporting aerial installation, ripcord under the sheath.


  • Accurate fiber excess length ensures good performance of tensile strength and temperature.
  • High strength loose tube, hydrolysis resistant, with special tube filling compound for critical fiber protection.
  • FRP as the central strength member.
  • Water blocking yarn and tape protect the cable from water.
  • 100% cable core filling.


  • This specification covers the general requirements of Figure 8 self-supporting cable for aerial installations.
