Editing Events
There may be cases where, because the backscattering light level is too small at a reflection point
in an optical fiber cable, 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:
• Insert events
• Delete events
• Edit event markers
• Fix event positions
