24-144 Core Micro Blown Cable

The 24–144 Core Micro Blown Cable is specifically designed for high-density fiber optic network expansion using microduct systems. With a compact, lightweight, and flexible construction, it supports air-blown installation into 10/12 mm microducts, minimizing civil works while maximizing deployment speed and scalability. Ideal for FTTx, metro networks, and 5G infrastructure requiring large core counts in tight spaces.

1. Structure & Design

• Core Configuration:

  • Loose tube construction with 4–12 tubes, each containing 2–12 fibers

  • Central strength member for structural stability

  • Total fiber count: 24 to 144 cores

• Tube Filling:

  • Each loose tube is filled with thixotropic gel to prevent water ingress and cushion fibers

• Sheath:

  • Outer sheath made of ultra-low friction LSZH or TPU, optimized for air blowing

  • Designed for use in 10 mm / 12 mm inner diameter microducts

• Outer Diameter:

  • Typically ranges from 5.5 mm to 8.5 mm, depending on fiber count

• Weight:

  • Lightweight design, approximately 25–45 kg/km

• Fully Dielectric (Optional):

  • No metal parts, safe near electrical infrastructure

• Color Coding:

  • Complies with IEC or customer-specific standards

2. Applications

• FTTH/FTTB multi-user connections

• Metro access and backbone networks

• 5G small cell and base station backhaul

• Campus or enterprise multi-core fiber backbones

• Network densification in existing microduct infrastructure

3. Advantages

• Supports up to 144 fibers in a compact, blowable design

• High blowing performance: long installation distances with low friction

• Fast deployment: no digging or splicing during duct expansion

• Scalable architecture: add fibers as needed, no need to replace cables

• Lightweight and flexible: ideal for congested or complex microduct routes

• Flame-retardant and UV-resistant: suitable for indoor and outdoor use

4. FAQs

• Q1: How far can this cable be blown in one shot?
  Under optimal conditions, up to 1500 meters or more, depending on duct condition, blowing machine, and number of bends.
• Q2: What duct sizes are required?
  Designed for microducts with 10 mm or 12 mm inner diameter.
• Q3: Is the cable waterproof?
  Yes. The loose tubes are gel-filled, and optional dry water-blocking yarns are available.
• Q4: Can I request a fully dielectric version?
  Yes. We offer metal-free constructions to ensure no EMI and safe deployment near electrical cables.
• Q5: Can this cable be customized for color, fiber type, or connectors?
  Absolutely. We can tailor fiber type (G.652D, G.657A1/A2, OM3, etc.), jacket color, and provide pre-terminated ends if required.
