9.11 Non-reflection Threshold (splice loss detecting
threshold) Configuration
This configuration has direct impact on the listing of insertion loss events. Only
events greater than this threshold will be listed. The value configuration zone is 0.00
to 5.00dB
The default value is 0.20dB.
9.12 Reflection Threshold (Reflection detecting
threshold) Configuration
This configuration has direct impact on reflection events listing. Only reflection
events greater than this threshold will be displayed in events list. The value
configuration zone is -10dB to -65dB
The default value is -52.00dB
9.13 End Threshold (optical fiber end detecting
threshold) Configuration
This threshold is the end threshold of optic fiber. If the end threshold equals 3.0dB,
then the first event with insertion loss greater than 3dB will be considered as the end
of the optic fiber. The value configuration zone is 0.0dB to 20.0dB
The default value is 3.00dB.
9.14 Load Default
In OTDR Setup surface, there are 3 “default” button, corresponding to scatter
coefficient (back scatter), non-reflection threshold (splice loss detecting threshold),
reflection threshold (reflection detecting threshold) and end threshold (optical fiber
end detecting threshold).
