NUMBER OF
ADAPTERS
NUMBER OF
SPLICES
If the selected limit uses a calculated loss limit, enter the number of
adapters and splices that will be added to the fiber path after the
reference is set. Figure 7-3 shows an example of how to determine the
NUMBER OF ADAPTERS setting.
Loss/length test limits that include maximum values for the loss per km,
loss per connector, and loss per splice use a calculated limit for overall loss.
Only limits with all three values use a calculated loss limit. For example,
fiber backbone limits use a calculated loss limit. The OVERALL LOSS value
should be N/A in these limits. If a loss value is entered, it is ignored.
These settings do not apply to Far End Source mode because the loss per
km calculation requires a length measurement, and length is not
measured in Far End Source mode.
To see the limit’s values, select TEST LIMIT on the Loss/Length tab; then
press
A

Reference test
cord length
(optional)
After you set a reference, you can enter the lengths of the reference test
cords used. The lengths are saved with results to meet TSB-140 reporting
requirements for fiber test results.

Wavelength In Smart Remote and Loopback modes, the tester automatically tests at
both wavelengths supported by the installed module. In Far End Source
mode, the tester prompts you to select a wavelength after you start a test.
