Air Blown Fiber (ABF) Underground Solution
Air Blown Fiber (ABF) is a modern underground fiber installation system where optical cables are blown through microducts using compressed air. It enables faster deployment, lower civil cost, and easy future expansion without re-digging.
1. Telecom Manholes
Access chambers installed every 100–300 meters for duct routing and maintenance.
Protect duct joints
Allow sectional cable blowing
Enable easy access and troubleshooting
2. Microduct Pipe
HDPE ducts designed for air-blown fiber installation.
Reduces installation cost
Supports future expansion
Avoids repeated excavation
Ideal for backbone and urban networks
3. Microduct Connectors
Used to join microduct sections securely.
Air-tight and water-blocking
Push-fit design
Maintains air pressure during blowing
4. Microduct Closures
Protective enclosures installed inside manholes.
Prevent water entry
Secure duct joints
Support branching and expansion
5. Cable Blowing
Fiber is installed using blowing machine and compressed air.
500m–2000m per section
Faster than traditional pulling
Reduces cable stress and damage
6. Duct Rodder
Fiberglass tool used before installation.
Checks blockage
Tests route continuity
Ensures smooth blowing process
7. Air Compressor
Provides required air supply for installation.
10–15 bar pressure
1–3 m³/min airflow
Clean, moisture-free air
