  31. Troubleshooting

  32. Start with basic information: • What Model Number? • What Power Supply? • Fiber Type? • Instruction Manual? • Pin-outs

  33. Things To Check: • LED Indicators: • OLI Optical Loss Indicator • VLI Video Loss Indicator • PWR Power Indicator

  34. Things To Check: • Transmission Distance? • What Splices and Patches are in the system? • Loss Budget (Calculated vs. Actual)

  35. More detailed troubleshooting: • Patch cords • Proper audio balance • Misaligned connectors • 75 ohm video termination • 120 ohm RS485 (RS422) data terminations • Physical damage (Shock, water…)

  36. Diagnostic Indicators

  37. DiagnosticsModule Bi-directional VLI OLI Fiber Video Data Power Bi-Directional Module VF-1400T
