Super Mini Uni-tube Air Blown Cable

The Super Mini Uni-tube Air Blown Cable is a highly efficient solution for FTTx and access networks, offering outstanding installation performance and mechanical protection in an ultra-slim design. Featuring a central loose tube with up to 12 fibers, this cable is optimized for air-blown installation into microducts as small as 5 mm in diameter. Its low-friction outer sheath ensures long blowing distances, even through complex duct paths.

1. Structure & Design

• Core Design:

  • • Central loose tube construction housing 2 to 12 fibers

    • Filled with thixotropic jelly for fiber protection and water blocking

• Outer Sheath:

  • • Made of ultra-low friction LSZH or TPU material

    • Designed for optimal blowing performance in narrow ducts

• Diameter & Weight:

  • • Outer diameter: typically 2.4 mm to 3.0 mm

    • Extremely lightweight: < 12 kg/km

• Color Coding:

  • • Fiber color coding complies with IEC 60304 or customizable per project

• Water Resistance:

  • • Water-blocking gel and sheath provide protection against moisture ingress

• No Metallic Components:

• • • Fully dielectric design, safe for use near electrical infrastructure

2. Applications

• FTTH (Fiber to the Home) microduct networks
• FTTB / FTTO deployment in buildings or campuses
• 5G backhaul and small cell interconnects
• High-density urban fiber rollouts
• Indoor/outdoor last-mile fiber installations

3. Advantages

• Ultra-small and lightweight: fits easily into 5 mm or smaller ducts
• Long air-blowing distances: over 1000 meters per shot possible
• Simple, uni-tube design: reduces material usage and enhances flexibility
• Low friction sheath: optimized for high-speed, low-pressure blowing
• Fast and non-disruptive installation: no trenching or heavy tools required
• Fully dielectric: immune to electromagnetic interference (EMI)

4. FAQs

• Q1: What is the main difference between Super Mini Uni-tube and EPFU cables?
  EPFU is even thinner and often uses tight-buffered fibers, while Super Mini Uni-tube uses a loose tube structure for better mechanical protection and more stable performance in outdoor conditions.

  Q2: What’s the minimum duct size required?
  Typically installed in microducts with inner diameters of 5–7 mm.

  Q3: Can this cable be used outdoors?
  Yes. The TPU/LSZH sheath provides UV resistance and moisture protection for indoor and outdoor use.

  Q4: Is the cable flame-retardant?
  Yes, when using LSZH material, it meets relevant IEC fire safety standards for indoor deployment.

  Q5: Can you supply pre-terminated versions?
  Yes, we offer factory pre-terminated options with SC, LC, FC, or MPO connectors for rapid deployment.
