Course Outline
Fiber Fundamentals for OT Troubleshooting
- The role 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, signal degradation, and intermittent faults
- Distinguishing between issues OT teams can diagnose in the field and those requiring contractor repair
Safe Handling, Inspection, and Cleaning
- Eye safety, laser safety, and the safe use of fiber testing equipment
- Proper handling of patch cords, connectors, ports, and jumpers
- Inspecting connector end faces for dirt, contamination, and physical damage
- Correctly cleaning connectors and verifying readiness for retesting
Essential Diagnostic Tools
- Using a visual fault locator to detect visible breaks and severe bends
- Employing an optical power meter and light source to verify signal presence and basic loss
- Using an inspection scope to assess connector condition prior to testing
- Understanding OTDRs—what they measure, how to interpret basic results, and when to escalate for professional OTDR testing
Practical Troubleshooting Workflow
- Confirming symptoms and collecting relevant data from the affected link
- Implementing a check, inspect, clean, and retest workflow
- Isolating potential causes such as dirty connectors, excessive loss, macro bends, or fiber breaks
- Distinguishing fiber issues from port, transceiver, or device-related problems
Field Scenarios, Documentation, and Escalation
- Troubleshooting scenarios involving no link, intermittent communication, and high attenuation
- Recording test results and observations in a clear field report
- Communicating findings to internal support teams or external contractors
- Knowing when to cease testing and escalate for repair or specialist diagnostics
Hands-On Practice and Review
- Guided exercises based on typical OT fiber fault scenarios
- Applying the full troubleshooting workflow from symptom identification to escalation decisions
- Review of best practices, common errors, and next steps
Requirements
- A fundamental understanding of network infrastructure and communication links
- Some experience in diagnosing network or OT communication issues in field settings
- Basic hands-on experience with cabling, ports, and network devices
Target Audience
- OT technicians
- Network and communications support staff
- Field personnel responsible for initial fiber issue diagnosis
