7.2 Editing Events
There may be cases where, because the backscattering light level is too small at a reflection point in
an optical fiber, the reflection cannot be detected as an event, or there may be cases where noise is
detected as an event.
In such cases, you can adjust the events by editing them as follows:
• Inserts events
• Deletes events
• Edit event markers
• Turn the event position fix feature on and off
