Fiber Optic Technology Course

Lesson 1 • Basic Fibre Optic Cable Structure

Identifies core, cladding, coating, and buffer layers and their respective roles. Connects material composition to optical and mechanical performance.

Lesson 2 • Refraction and Snell's Law

Explains how light bends at material boundaries using Snell's Law. Directly enables understanding of total internal reflection inside fibre cores.

Lesson 3 • Light Sources Used in Fibre Systems

Introduces LEDs and laser diodes as the primary optical transmitters in fibre systems. Compares coherence, bandwidth, and coupling efficiency of each source type.

Lesson 4 • Total Internal Reflection Principle

Demonstrates how light is trapped inside a fibre core when the critical angle is exceeded. This principle is the operational foundation of all fibre optic transmission.

Lesson 1 • Multimode Fibre Variants

Covers step-index and graded-index multimode fibres and their modal dispersion profiles. Connects fibre geometry to bandwidth-distance limitations in enterprise networks.

Lesson 2 • Specialty Fibre Types

Introduces polarization-maintaining, photonic crystal, and bend-insensitive fibres for specialised applications. Expands the student's selection toolkit beyond standard fibre categories.

Lesson 3 • Cable Construction and Jacket Designs

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

Lesson 4 • Single-Mode Fibre 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 • Polarisation Mode Dispersion

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

Lesson 2 • Optical Power and Decibel Maths

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

Lesson 3 • Modal and Chromatic Dispersion

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

Lesson 4 • Link Loss Budget Calculation

Applies attenuation and connector loss values to determine whether a link meets power margin requirements. Students complete end-to-end budget worksheets for realistic scenarios.

Lesson 1 • Fibre Optic Connector Types

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 fibre distribution hub design, labelling conventions, and cable management best practices. Connects physical infrastructure organisation to troubleshooting efficiency.

Lesson 1 • Direct-Buried and Underground Installation

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

Lesson 2 • Fibre 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 fibre runs. Prevents cable damage caused by exceeding bend radius or tensile load.

Lesson 4 • Aerial Fibre 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 fibre 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 fibre. 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 fibre 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 fibre-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 fibre pair.

Lesson 1 • Connector Inspection and Cleaning

Uses fibre 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 fibre link faults. Reduces mean time to repair by eliminating guesswork and focusing on measurable symptoms.

Lesson 3 • Preventive Maintenance Programmes

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

Lesson 4 • Fibre 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.
