Lesson 2 • Specialty Fiber Types

Introduces polarization-maintaining, photonic crystal, and bend-insensitive fibers for specialized applications. Expands the student's selection toolkit beyond standard fiber categories.

Lesson 3 • Cable Construction and Jacket Designs

Describes loose-tube, tight-buffered, ribbon, and armored cable constructions. Links mechanical design choices to installation environment requirements.

Lesson 4 • Single-Mode Fiber Characteristics

Examines the small core diameter and single propagation path that enable long-distance, high-bandwidth transmission. Establishes when single-mode is the preferred choice.

Lesson 1 • Polarization Mode Dispersion

Explains how birefringence in single-mode fiber causes pulse broadening at high bit rates. Addresses measurement and compensation approaches for high-speed links.

Lesson 2 • Optical Power and Decibel Math

Teaches dBm, dB, and loss ratio calculations essential for link engineering. Students practice converting between linear power and logarithmic units.

Lesson 3 • Modal and Chromatic Dispersion

Distinguishes modal dispersion in multimode fiber from chromatic dispersion in single-mode fiber. Connects dispersion magnitude to achievable data rates and reach.

Surveys LC, SC, ST, FC, MPO, and other common connector styles and their keying and polish types. Matches connector selection to transceiver interfaces and panel designs.

Lesson 2 • Passive Optical Components

Introduces couplers, splitters, WDM filters, attenuators, and isolators used in optical networks. Explains insertion loss and isolation specs that govern component selection.

Lesson 3 • Mechanical and Fusion Splicing

Compares mechanical splice assemblies with fusion splicing for permanent low-loss joints. Covers arc fusion machine operation, splice protection, and quality verification.

Lesson 4 • Patch Panels and Distribution Frames

Covers fiber distribution hub design, labeling conventions, and cable management best practices. Connects physical infrastructure organization to troubleshooting efficiency.

Lesson 1 • Direct-Buried and Underground Installation

Details trenching depth, bedding material, warning tape placement, and armored cable requirements. Ensures buried plant survives environmental and mechanical stress over its service life.

Lesson 2 • Fiber Handling and Bend Radius Control

Enforces minimum bend radius rules during pulling, routing, and storage to prevent microbend losses. Connects improper handling directly to measurable performance degradation.

Lesson 3 • Conduit and Innerduct Installation

Covers conduit fill calculations, pulling tension limits, and innerduct selection for protected fiber runs. Prevents cable damage caused by exceeding bend radius or tensile load.

Lesson 4 • Aerial Fiber Installation Methods

Explains lashing, self-supporting ADSS, and figure-eight cable deployment on utility poles. Addresses sag, tension, and clearance requirements for aerial plant safety.

Lesson 1 • OTDR Trace Interpretation

Trains students to identify connectors, splices, bends, and fiber ends on an OTDR trace. Quantifies event loss and reflectance values for pass/fail certification.

Lesson 2 • Visual Fault Locators and Continuity

Uses visible red-light sources to identify breaks, bends, and connector faults quickly. Establishes the first-pass inspection step before deploying precision instruments.

Lesson 3 • OTDR Principles and Setup

Explains how an OTDR uses backscattered light to locate and quantify events along a fiber. Covers pulse width, range, and dead zone settings for accurate measurements.

Lesson 4 • Optical Power Meter Measurements

Teaches insertion loss measurement using a calibrated light source and power meter pair. Students perform end-to-end loss tests and compare results to the loss budget.

Lesson 1 • Network Topology Fundamentals

Compares point-to-point, ring, star, and mesh fiber topologies for reliability and cost trade-offs. Provides the architectural vocabulary used throughout network design work.

Lesson 2 • Passive Optical Network Architecture

Explains PON splitter ratios, optical line terminal placement, and reach limits for fiber-to-the-premises deployments. Connects PON design to subscriber density and budget constraints.

Lesson 3 • Design Documentation and As-Built Records

Establishes standards for route maps, splice schedules, and test result documentation. Accurate records reduce troubleshooting time and support future network expansion.

Lesson 4 • Wavelength Division Multiplexing Design

Covers CWDM and DWDM channel plans, amplifier placement, and dispersion compensation in WDM links. Enables students to design multi-channel systems on a single fiber pair.

Lesson 1 • Connector Inspection and Cleaning

Uses fiber inspection microscopes and cleaning tools to identify and remove contamination on end-faces. Contamination is the leading cause of elevated insertion loss in installed systems.

Lesson 2 • Systematic Fault Isolation Process

Introduces a structured divide-and-conquer troubleshooting methodology for fiber link faults. Reduces mean time to repair by eliminating guesswork and focusing on measurable symptoms.

Lesson 3 • Preventive Maintenance Programs

Establishes inspection schedules, cleaning intervals, and performance trending to prevent unplanned outages. Proactive maintenance extends infrastructure life and reduces emergency repair costs.

Lesson 4 • Fiber Break Repair Procedures

Covers locating a break with OTDR, accessing the cable, re-splicing, and restoring the link to specification. Includes splice enclosure re-entry and re-sealing best practices.
