10 Dec Fiber Blowing Best Practices: The Complete Engineering Checklist for High-Performance Deployments

Posted at 12:53h in Cable Blowing by UPCOM Telekomunikasyon

Efficient fiber blowing is not only about using a powerful machine or high-quality fiber. Field performance depends on engineering discipline: correct duct–cable pairing, airflow capacity, lubrication strategy, mechanical limits, and environmental planning.This guide provides a complete engineering checklist used by professional FTTx, OSP, and backbone deployment teams worldwide.

Why Engineering Quality Determines Fiber Blowing Success

In real deployments, 20–30% performance loss comes not from the fiber itself, but from technical misconfigurations: poor duct preparation, incorrect fill ratio, low airflow, wrong lubrication, or ignoring bending/tensile limits.

Optimizing installation parameters increases blowing distance, reduces friction, prevents microbending, and protects the fibers during installation.

Comprehensive Fiber Blowing Checklist

This checklist applies to all modern cable-blowing machines used in FTTH, FTTB, backbone, and long-haul projects.

1. Cable & Duct Compatibility

Cable–duct fill ratio maintained at 40–60%
Duct inner surface checked (clean, dry, debris-free)
No ovalization or damage on duct entry
No tight bends in the first 3–5 meters
Correct duct diameter selected for the cable outer diameter

2. Air & Machine Setup

Compressor airflow capacity verified: 200–600 L/min
Air filtration and moisture traps active
Machine rollers/wheels/belts inspected for wear
Jetting head aligned perfectly with duct entry
Air pressure test completed before insertion
All safety stops and emergency controls tested

3. Lubrication Strategy

Lubricant compatible with dry-core or gel-filled designs

Lubrication applied continuously (not in a single spot)
Pre-lubrication done for long routes or old ducts
Avoid over-lubrication, which can cause oscillation

Here is the list of UPCOM lubricants:

4. Mechanical Limits

Tensile rating checked from the manufacturer datasheet
Crush rating matches expected duct route pressure
Minimum bending radius respected along entire route
Installation speed kept within acceptable range
Drum handling done without additional tension

5. Environmental Conditions

Temperature suitable for jetting (extreme heat increases friction)
Humidity or condensation inside ducts eliminated
Duct route scanned for blockages or deformations
Avoid blowing during rain if ducts are not fully sealed

Here is the UPCOM air Cooler that helps you on your cable jetting blowing application

6. Pre-Start Procedures

Drum positioned to eliminate back tension
Drum brake calibrated for smooth rotation
Field team communication established
Test blowing done for the first 100–200 meters
Airflow and pressure monitored during test

7. Post-Blowing Procedures

Fiber end inspected for integrity
Excess fiber length managed according to project requirements
Full route documented for future maintenance
Machine counters reset and logged

Engineering Always Outperforms Cheap Materials

Lowering fiber cost rarely improves project performance.
Optimizing engineering parameters consistently delivers:

Longer blowing distances
Lower installation time
Reduced risk of fiber damage
Higher network lifetime performance

Smart engineering beats cheap materials. Every time.
