The 24–144 Core Micro Blown Cable is specifically designed for high-density fiber optic network expansion within microduct systems. With a compact, lightweight, and flexible structure, it supports air-blown installation into 10/12 mm microducts, minimizing civil works while maximizing deployment efficiency and scalability.

It is widely used in duct fiber optic cable systems where high capacity and limited duct space are critical.

For a comparison between air-blown and traditional solutions, see our guide on Microduct vs Traditional Fiber Optic Cable.

Structure & Design

Core Configuration

• Stranded loose tube design with 4–12 tubes
• Each tube contains 2–12 fibers
• Central strength member for enhanced mechanical stability
• Total fiber count: 24 to 144 cores

Tube Filling

• Thixotropic gel-filled loose tubes
• Prevents water ingress and protects fibers from mechanical stress

Outer Sheath

• Ultra-low friction LSZH or TPU sheath optimized for air blowing
• Designed for installation in 10 mm / 12 mm microducts

Outer Diameter

• Approx. 5.5 mm to 8.5 mm (depending on fiber count)

Weight

• Lightweight design: approx. 25–45 kg/km

Fully Dielectric (Optional)

• Metal-free structure available
• Ideal for deployment near power lines or EMI-sensitive environments

Color Coding

• • Standard compliant with IEC or customizable

🔹 Applications

• FTTH / FTTB multi-user distribution networks
• Metropolitan access and backbone networks
• 5G small cell and base station backhaul
• Campus and enterprise fiber backbone
• Network densification in existing microduct infrastructure

 Commonly deployed alongside microduct fiber optic cable solutions for scalable network expansion.

Advantages

• Supports up to 144 fibers in a compact, blowable design
• Excellent blowing performance with low-friction sheath
• Reduced installation cost (no trenching or re-ducting)
• Scalable architecture: expand capacity without replacing cables
• Lightweight and flexible for complex duct routes
• Flame-retardant and UV-resistant for indoor & outdoor use

Blowing Performance

• Optimized for long-distance air blowing
• Low friction outer jacket reduces installation resistance
• Suitable for complex duct routes with multiple bends

 Compared to traditional installation methods used in duct fiber optic cable systems, air blowing significantly reduces mechanical stress.

FAQs
