Intermittent Link/High Errors:
- Clean fiber connectors meticulously.
- Check for damaged fiber cables or connectors (bends, breaks).
- Verify DOM values (especially Rx Power – might be too low or too high causing saturation).
- Check module temperature.
DOM Values Not Reading:
- Ensure the host device supports DOM/DDM.
- Verify compatibility (some older hosts have limited support).
