The fibers, are positioned in a loose tube made of a high modulus plastic. The interstice inside and outside of the tubes are filled with a water-resistant filling compound. A steel wire, coated with polyethylene if necessary locates in the center of core as a strength member. Tubers (and fillers) are stranded around the strength member to form a compact and circular cable core. The plastic coated steel tape is wrapped over the core and extruded into a polyethylene sheath to form a cable. The galvanized steel stranding wires is applied as the messenger. Finally, the messenger and the cable is linked together to form type figure -8 cable..
All section water blocking provides reliable performance of moisture-proof and water block.
Special filling gel filled loose tube provide perfect optical fiber protection.
Longitudinal corrugated steel tape gives desirable crush resistance.
Figure 8 self-supporting structure presents high tensile strength and enables easy and cost saving aerial installation.
Strict craft and raw material control enable lifespan over 30 years.
