Course Outline
Fiber Fundamentals for OT Troubleshooting
- The role of fiber in OT environments and the impact of link issues on operations
- Practical field distinctions between single-mode and multimode fiber
- Frequent causes of communication loss, degradation, and intermittent faults
- Distinguishing between issues OT teams can diagnose in the field versus those requiring contractor repair
Safe Handling, Inspection, and Cleaning
- Eye and laser safety protocols, including the safe use of fiber test equipment
- Correct handling of patch cords, connectors, ports, and jumpers
- Examining connector end faces for dirt, contamination, or damage
- Proper connector cleaning techniques and verification for retesting
Essential Diagnostic Instruments
- Employing a visual fault locator to detect visible breaks and severe bends
- Using an optical power meter and light source to verify signal presence and basic loss
- Utilizing an inspection scope to assess connector condition prior to testing
- OTDR awareness: understanding outputs, interpreting basic results, and recognizing when to escalate for OTDR testing
Practical Troubleshooting Workflow
- Verifying 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
- Differentiating fiber issues from port, transceiver, or device malfunctions
Field Scenarios, Documentation, and Escalation
- Addressing 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
- Recognizing 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 complete troubleshooting workflow from symptom identification to escalation decision
- Review of best practices, common errors, and recommended next steps
Requirements
- A foundational understanding of network infrastructure and communication links
- Practical experience in diagnosing network or OT communication issues in the field
- Basic hands-on familiarity with cabling, ports, and network devices
Audience
- OT technicians
- Network and communications support personnel
- Field staff responsible for initial fiber issue diagnosis
