9.12 Reflection Threshold (Reflection Detection 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 threshold range is from -10dB to -65dB
Note:
The default value is -52.00dB
9.13 End Threshold (Optical Fiber End-Face Detection Threshold)
Configuration
This threshold is the end-face threshold of optical fiber. If the end-face threshold equals 3.0dB, then the
first event with insertion loss greater than 3dB will be considered as the end of the optical fiber. The
available values are between 0.0dB to 20.0dB.
Note:
The default value is 3.00dB.
9.14 Load Default
In the OTDR Setup interface, there are three “default” options. Each option corresponds to scatter
coefficient (back scatter) non-reflective events’ thresholds:
1) Splice Loss Detecting Threshold
2) Reflection Threshold (reflection detecting threshold)
3) End Threshold (optical fiber end detecting threshold).
