Lesson 2 • Mechanical Splicing Methods

Introduces index-matching gel, V-groove, and rotary mechanical splice devices as alternatives to fusion. Students apply mechanical splices in field scenarios where fusion is impractical.

Lesson 3 • Splice Loss Testing and Verification

Applies OTDR and optical loss test sets to verify splice quality after completion. Students interpret test results and re-splice when loss exceeds acceptance thresholds.

Lesson 4 • Fusion Splicing Process

Covers arc fusion splicer setup, fiber alignment, arc discharge, and splice quality estimation. Students operate a fusion splicer to produce splices below 0.1 dB loss.

Lesson 1 • Wavelength Division Multiplexing Design

Covers CWDM and DWDM channel plans, spacing standards, and amplifier placement for high-capacity links. Students design a WDM channel plan for a given capacity requirement.

Lesson 2 • Outside Plant Cable Route Planning

Addresses aerial, direct-buried, and conduit installation methods and route survey requirements. Students produce a cable route plan with splice point and handhole locations.

Lesson 3 • Network Topology and Architecture

Compares point-to-point, ring, star, and mesh fiber topologies for reliability and cost. Students select topology based on redundancy requirements and traffic patterns.

Lesson 4 • Inside Plant and Data Center Design

Covers structured cabling standards, horizontal and backbone fiber runs, and data center interconnect design. Students design a fiber distribution layout for a multi-floor building.

Lesson 1 • Aerial and Underground Installation

Addresses lashing, self-supporting cable, direct-buried, and conduit installation field procedures. Students follow safety and regulatory guidelines for each installation environment.

Lesson 2 • Acceptance Testing and Documentation

Compiles test results into structured acceptance reports and as-built documentation packages. Students deliver a complete documentation set meeting project handover requirements.

Lesson 3 • Cable Pulling and Blowing Techniques

Covers pulling tension limits, lubricants, figure-eight coiling, and air-blown fiber installation. Students apply correct techniques to avoid fiber damage during installation.

Lesson 4 • OTDR Operation and Trace Analysis

Teaches OTDR parameter setup, event identification, and fault localization from trace data. Students diagnose connector, splice, and fiber faults from OTDR traces.

Lesson 1 • Common Fiber Fault Types and Causes

Catalogs breaks, high-loss splices, dirty connectors, macrobends, and water ingress as primary fault types. Students match fault symptoms to probable causes using diagnostic evidence.

Lesson 2 • Systematic Fault Isolation Methodology

Introduces a structured divide-and-conquer approach to isolating fiber link faults. Students apply the methodology to reduce mean time to repair on complex fiber networks.

Lesson 3 • Preventive Maintenance Programs

Establishes scheduled inspection, cleaning, and testing routines to prevent fiber link degradation. Students design a maintenance schedule aligned with network criticality levels.

Lesson 4 • Fiber Repair Procedures

Covers emergency re-splicing, connector replacement, and cable section restoration in the field. Students execute a repair workflow that restores link performance to specification.
