Events Summary
Beginning of fiber
Splice
Connector / Coupler
Macrobend
End of fiber
Events will be highlighted if the respective event is greater than the relevant setting in the Pass/Fail menu.
Pass/Fail Setup
Pass/Fail settings are accessed as shown in Figure 3.
Pass/Fail analysis is dependent on the settings as shown in Figure 4.
Figure 3 Figure 4
Ins. Loss
Measured events with insertion loss greater than this setting will be displayed red.
Reflectance
Measured events with reflectance greater than this setting will be displayed red.
Total Attn.
Measured links with a total attenuation greater than this setting will be displayed in red.
Total Loss
Measured links with a total loss greater than this setting will be displayed in red.
Total ORL (Optical Return Loss)
If the total ORL for the link is equal to or greater than this setting the link will be displayed red.
Thres. On/Off
Enable / Disable Pass/Fail function. On provides Pass/Fail analysis. Off disables the analysis.

Macrobend Analysis
Macrobend Analysis will find events that are high losses at 1550nm and little or no loss at 1310nm. To activate this feature set the
Wavelength setting to 1310+1550nm as shown in Figure 5.
Use the Delta to set the Macrobend sensitivity. Lower Deltas will find progressively smaller Macrobends. Please note when
single wavelength is selected, Delta is not available for setting. Macrobend analysis is not available in 1310nm and 1550nm
measurements.
Figure 6 shows an example of two Macrobends in Link Viewer mode.
