Fault Events
Display
Events that are greater than or equal to the specified threshold (or reflections that are less than or
equal to the specified threshold) are displayed as fault events.
Off: Events that have exceeded their threshold values are not displayed with an asterisk
attached to them.
On: Events that have exceeded their threshold values are displayed with an asterisk
attached to them.
Splice Loss and Return Loss
Set the threshold values that are used to display events as faults.
Splice loss: The range is 0.01 dB to 9.99 dB.
Return loss: The range is 20 dB to 70 dB.
Because the end of fibers is handled as either a splice loss or a reflection, there is no fault event
just for the end of fibers.
PASS/FAIL Judgement
If you have turned the fault event display on, you can display the result of PASS/FAIL judgment in
the lower left of the waveform display area.
Display: FAIL or PASS and the number of fault events are displayed.
Hide: The judgment is not displayed.
