Supplier's note

  1. Three Technical Breakthroughs:

    • Twisted Pair Design: Reduces crosstalk by 30% compared to unshielded cables, ensuring signal integrity over long distances.
    • Quadruple Shielding (Pro Model): Blocks 95% of external EMI, critical for industrial environments with heavy machinery.
    • Armored PE Sheath (Pro Model): Withstands 20% more physical stress than standard jackets, ideal for direct burial in rocky terrain.

  2. Version Selection Guide:

    • Base Model: Ideal for small offices or residential setups requiring up to 50 pairs. Its standard PE jacket and single-layer shielding balance cost and performance.
    • Advanced Model: Suited for medium-scale data centers or outdoor telecom networks needing 100–600 pairs. Enhanced shielding and UV protection extend lifespan in harsh sunlight.
    • Pro Model: Designed for industrial and large-scale deployments (e.g., smart cities, mining). The armored sheath and quadruple shielding enable direct burial while maintaining signal clarity in extreme temperatures.

With the Pro Model’s quadruple shielding, you can ensure secure data transmission in electromagnetic-heavy factories. The Advanced Model’s UV-resistant jacket doubles outdoor durability compared to non-reinforced alternatives. Choose based on pair requirements and environmental conditions—whether safeguarding signals in a data center or burying cables underground.
