Fiber Optic Cable Blowing Training

Lesson 1 • Fibre Optic Cable Construction

Examines buffer layers, strength members, jackets, and loose-tube vs. tight-buffered designs. Understanding construction prevents damage during blowing operations.

Lesson 2 • Fundamentals of Light Transmission

Covers total internal reflection, refractive index, and how light travels through glass fibre. Establishes the physics basis needed for all subsequent installation concepts.

Lesson 3 • Blown Fibre vs. Traditional Installation

Compares air-blown, pull, and push methods across cost, scalability, and risk factors. Establishes the business and technical case for blown fibre adoption.

Lesson 1 • Fibre Glass Fragment Hazards

Identifies risks from cleaved fibre ends, glass splinters, and eye contamination. Proper hazard awareness prevents injuries throughout all installation tasks.

Lesson 2 • Site Safety Assessment and Permits

Teaches hazard identification, confined space entry rules, and work permit processes for fibre installation sites. Ensures regulatory compliance before equipment deployment.

Lesson 3 • Compressed Air and Pressure Safety

Covers pressure vessel hazards, hose failure risks, and safe operating pressure ranges for blowing equipment. Connects directly to equipment setup covered in the next chapter.

Lesson 1 • Micro-Duct Types and Specifications

Compares rigid, semi-rigid, and flexible micro-duct materials, sizes, and pressure ratings. Correct duct selection directly determines blowing performance and cable protection.

Lesson 2 • Duct Network Topology Planning

Covers point-to-point, branching, and ring topologies for micro-duct networks. Topology decisions affect blowing distance, pressure requirements, and future upgrade paths.

Lesson 3 • Duct Installation and Jointing

Teaches trenching, conduit placement, push-fit jointing, and sealing techniques for micro-duct systems. Proper jointing prevents air leaks that degrade blowing performance.

Lesson 4 • Duct Repair and Maintenance

Covers fault diagnosis, coupling repair, and duct replacement procedures for damaged sections. Maintenance skills extend infrastructure life and preserve blowing performance.

Lesson 1 • Air Compressor Selection and Setup

Covers compressor capacity, duty cycle, moisture management, and connection to blowing machines. Correct compressor selection prevents pressure drops that stall cable installation.

Lesson 2 • Equipment Inspection and Maintenance

Establishes pre-use inspection checklists, roller cleaning, and scheduled maintenance intervals for blowing machines. Well-maintained equipment ensures consistent installation performance.

Lesson 3 • Blowing Machine Components and Functions

Identifies drive rollers, air chambers, control panels, and pressure regulators on blowing machines. Component knowledge is prerequisite to correct setup and fault diagnosis.

Lesson 1 • Cable End Preparation Techniques

Teaches jacket stripping, end-cap removal, and nose-cone attachment for blown fibre cable ends. Correctly prepared ends feed smoothly into blowing machines without snagging.

Lesson 2 • Cable Reel Management and Storage

Covers reel inspection, storage orientation, temperature limits, and minimum bend radius during handling. Correct reel management prevents pre-installation damage that causes blowing failures.

Lesson 3 • Bend Radius and Tension Management

Explains maximum installation load, bend radius limits, and how to monitor tension during blowing. Exceeding limits causes micro-bending losses that degrade long-term optical performance.

Lesson 1 • Blowing Technique for Long Runs

Addresses pressure optimisation, intermediate assist points, and speed ramping for runs exceeding 500 metres. Long-run techniques maximise distance while protecting cable integrity.

Lesson 2 • Machine Setup and Pre-Blow Checks

Covers duct connection, cable threading, pressure setting, and team communication before blowing begins. Thorough pre-blow checks prevent mid-run failures and cable damage.

Lesson 3 • Multi-Cable and Bundle Blowing

Covers simultaneous and sequential blowing of multiple cables into shared or adjacent ducts. Bundle techniques increase installation efficiency on high-density routes.

Lesson 4 • Blowing Technique for Short Runs

Teaches controlled speed and pressure settings for runs under 300 metres in straight and lightly curved ducts. Short-run mastery builds the muscle memory needed for longer, complex installations.

Lesson 1 • Duct Blockage Diagnosis and Clearing

Covers rodding, air purging, and camera inspection to locate and clear duct obstructions. Blockage resolution restores duct integrity before re-attempting cable installation.

Lesson 2 • Cable Damage Assessment and Recovery

Teaches visual and optical inspection of cable after a failed run to assess damage extent. Recovery decisions determine whether cable can be reused or must be replaced.

Lesson 3 • Pressure and Airflow Fault Diagnosis

Identifies causes of pressure loss including leaking joints, damaged hoses, and compressor faults. Restoring correct airflow is essential before resuming any blowing operation.

Lesson 4 • Identifying Installation Stalls

Teaches recognition of stall symptoms through pressure gauges, speed meters, and cable counter readings. Early stall identification prevents cable damage from continued machine force.

Lesson 1 • Acceptance Testing and Documentation

Guides compilation of test results, as-built drawings, and handover documentation packages. Complete documentation is required for client acceptance and future maintenance reference.

Lesson 2 • Optical Loss Testing Fundamentals

Introduces insertion loss, return loss, and acceptable loss budgets for blown fibre installations. Loss testing confirms that installed cable meets design specifications before commissioning.

Lesson 3 • End-Face Inspection and Cleaning

Teaches connector end-face inspection using video microscopes and proper cleaning techniques. Contaminated end-faces are the leading cause of high insertion loss at connectors.
