Course Outline
Fiber Basics for OT Troubleshooting
- Applications of fiber in OT environments and the impact of link issues on operations
- Single-mode and multimode fiber explained in practical field terms
- Common causes of communication loss, degradation, and intermittent faults
- Distinction between issues OT teams can diagnose in the field versus those requiring contractor repair
Safe Handling, Inspection, and Cleaning
- Eye safety, laser safety, and safe operation of fiber test tools
- Proper handling of patch cords, connectors, ports, and jumpers
- Inspecting connector end faces for dirt, contamination, and damage
- Correctly cleaning connectors and confirming they are ready for retesting
Essential Diagnostic Tools
- Using a visual fault locator to identify visible breaks and severe bends
- Utilizing an optical power meter and light source to confirm signal presence and basic loss
- Employing an inspection scope to check connector condition prior to testing
- Understanding OTDR - interpreting basic results and knowing when to escalate for OTDR testing
Practical Troubleshooting Workflow
- Confirming symptoms and gathering relevant information from the affected link
- Applying a check, inspect, clean, retest workflow
- Isolating probable causes such as dirty connectors, excessive loss, macro bends, or fiber breaks
- Distinguishing likely fiber problems from port, transceiver, or device issues
Field Scenarios, Documentation, and Escalation
- Troubleshooting no link, intermittent communication, and high attenuation scenarios
- Recording test results and observations in a clear field report
- Communicating findings to internal support teams or external contractors
- Knowing when to stop testing and escalate for repair or specialist diagnostics
Hands-On Practice and Review
- Guided exercises using typical OT fiber fault scenarios
- Applying the full troubleshooting workflow from symptom identification to escalation decision
- Review of good practices, common mistakes, and next steps
Requirements
- Fundamental knowledge of network infrastructure and communication links
- Some prior experience troubleshooting network or OT communication issues in the field
- Basic hands-on experience with cabling, ports, and network devices
Audience
- OT technicians
- Network and communications support staff
- Field personnel tasked with first-line fiber issue diagnosis
