Setting the Analysis Detection Thresholds
Setting the Analysis Detection Thresholds
Note: This function is available in Advanced mode only.
To optimize event detection, you can set the following analysis detection
thresholds:
³
Splice loss threshold: To display or hide small non-reflective events.
³
Reflectance threshold: To hide false reflective events generated by
noise, transform non-harmful reflective events into loss events, or
detect reflective events that could be harmful to network and other
fiber-optic equipment.
³
End-of-fiber threshold: To stop the analysis as soon as an important
event loss occurs; for example, an event that could compromise signal
transmission toward the end of a network.

MPORTANT
The end-of-fiber (EoF) threshold that you define will be used in
Automatic mode and in Advanced mode if you let the application
evaluate the acquisition settings.
If you set this threshold, an EoF event will be inserted at the first
event for which the loss crosses the threshold. The application will
then use this EoF event to determine the acquisition settings.
