930XC Link Viewer
Display Mode
Events are presented by icons in link view, viewing each one of the events is the same as in trace view with the same hot
keys. The symbol indicates the selected event with event number. The overall fiber link information is shown in the black
line pictorial above the event link with relative position marks (white vertical lines) and distance information (total length and
location of selected event).
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.
Link Viewer is a graphical way of presenting OTDR test results. The user can manually switch between Link Viewer mode and
Trace mode by toggling the Display Mode setting as shown below in Figure 1.
Figure 1
The test settings in Link Viewer mode are the same as in Trace mode, parameters as Range, Pulse Width, Measuring Mode
(Averaging/ Real Time), Time, IOR etc. need proper configuration for reasonable test results. The user can start a test either
in Link Viewer Mode or Trace Mode. In Link Viewer mode, OTDR test results are presented in a way shown in Figure 2.

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.

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.
