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, degradation, and intermittent faults
  • Distinguishing between issues OT teams can diagnose in the field versus those requiring contractor repair

Safe Handling, Inspection, and Cleaning

  • Ensuring eye and laser safety, and the safe use of fiber test tools
  • 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 confirm signal presence and basic loss
  • Utilizing an inspection scope to assess connector condition prior to testing
  • OTDR awareness - interpreting basic results, understanding its capabilities, and knowing when to escalate for OTDR testing

Practical Troubleshooting Workflow

  • Confirming symptoms and gathering relevant data from the affected link
  • Applying a systematic check, inspect, clean, and retest workflow
  • Isolating likely causes such as dirty connectors, excessive loss, macro bends, or fiber breaks
  • Differentiating between fiber-specific problems and issues with ports, transceivers, or devices

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 effectively 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 complete troubleshooting workflow from symptom identification to escalation decision
  • Reviewing best practices, common pitfalls, and recommended next steps

Requirements

  • A foundational understanding of network infrastructure and communication links.
  • Some practical experience in troubleshooting network or OT communication issues in field settings.
  • Basic hands-on familiarity with cabling, ports, and network devices.

Target Audience

  • OT technicians
  • Network and communications support staff
  • Field personnel tasked with first-line diagnosis of fiber issues
