1.Central Steel Wire Reinforcement for Stable Tensile Performance
Built with a centralized steel strength member (optional PE sheath), the cable delivers excellent pull resistance during construction. The stranded structural design uniformly disperses pulling tension, avoiding concentrated stress on fiber cores. It adapts to long-distance duct traction and overhead aerial laying, effectively lowering fiber breakage risks and ensuring stable transmission for long-span outdoor network links.
2.PSP Corrugated Steel Tape Armor for Anti-Crush & Anti-Rodent Protection
The integrated longitudinal PSP steel tape forms a rigid protective layer, greatly improving pressure resistance and abrasion resistance. It shields internal fibers from sharp rock extrusion, ground settlement pressure and rodent gnawing damage. Meanwhile, the steel tape serves as a secondary moisture barrier, enabling reliable operation in rocky burial sites and pest-active duct environments.
3.Full-Cable Water-Blocking Structure for Humid Environment Adaptation
Equipped with dual waterproof protection of tube internal hydrophobic gel and core integral water-blocking compound, paired with PSP barrier isolation, the cable completely blocks longitudinal and lateral water penetration. It maintains ultra-stable signal transmission in high-humidity conditions and intermittently flooded pipelines. The inner gel buffer also permanently optimizes fiber bending performance, sustaining low-attenuation operation throughout the service cycle.
4.High-Density Compact Structure for Space-Saving Installation
Integrating 6 optical fibers in a single loose tube design, the cable achieves high fiber transmission density with a slim, lightweight body. Its streamlined structure simplifies transportation, storage and manual laying operations. Featuring flexible stranded construction, it supports smooth bending and routing in narrow cable trays and crowded pipeline systems, perfectly matching space-limited urban access network renovation and construction.
5.Strong Weather Resistance for All-Climate Outdoor Operation
Capable of continuous stable operation in temperatures from -40°C to +60°C, and supporting field installation at -10°C and above, the cable adapts to extreme cold, high heat and variable seasonal climates. The high-performance outer PE sheath resists UV aging, ozone erosion and chemical corrosion, avoiding cracking, deformation and aging failure under long-term outdoor exposure, minimizing later maintenance costs.
