Course Outline
Fiber Basics for OT Troubleshooting
- The role of fiber in OT environments and the operational impact of link issues.
- Practical field concepts of single-mode and multimode fiber.
- Common drivers 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 and laser safety protocols, and the safe operation of fiber test tools.
- Proper handling procedures for patch cords, connectors, ports, and jumpers.
- Techniques for inspecting connector end faces to detect dirt, contamination, or damage.
- Correct cleaning methods and verification that connectors are ready for retesting.
Essential Diagnostic Tools
- Utilizing a visual fault locator to spot visible breaks and severe bends.
- Using optical power meters and light sources to verify signal presence and assess basic loss.
- Employing inspection scopes to evaluate connector condition prior to testing.
- Understanding OTDR capabilities, interpreting basic results, and recognizing when to escalate for advanced OTDR testing.
Practical Troubleshooting Workflow
- Validating symptoms and collecting relevant data from affected links.
- Implementing a systematic check, inspect, clean, and retest process.
- Isolating likely root causes, such as dirty connectors, excessive loss, macro bends, or fiber breaks.
- Differentiating fiber-specific problems from port, transceiver, or device-related issues.
Field Scenarios, Documentation, and Escalation
- Addressing scenarios involving no link, intermittent communication, and high attenuation.
- Recording test results and observations in clear field reports.
- Effectively communicating findings to internal support teams or external contractors.
- Recognizing when to halt 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 initial symptom identification to escalation decisions.
- Reviewing best practices, common pitfalls, and recommended next steps.
Requirements
- Familiarity with network infrastructure and communication link fundamentals.
- Prior experience troubleshooting network or OT communication issues in field settings.
- Basic practical experience with cabling, ports, and network devices.
Target Audience
- OT technicians.
- Network and communications support staff.
- Field personnel responsible for initial fiber issue diagnosis.
