Splitter Setup
Splitter Ratios: Enter the ratios for up to three splitters.
You can enter ratios of 1x2 to 1x128 and 2x2 to 2x128. The
tester uses the ratios to estimate how the loss and other
effects of the splitter will affect the OTDR test results.
If you do not enter ratios, the tester identifies splitters as
large loss events.
DISCOVER: When you tap DISCOVER, the tester looks for
splitters on the fiber and uses their losses to identify their
ratios.
Manual
Settings:
Range
The Range is the maximum distance shown on the trace.
Select the range that is nearest to, but not less than, the
distance to the event you want to examine. If the tester
does not correctly identify the end event, select the next
higher range, then do the OTDR test again.
Auto: The tester selects a range that gives the best possible
view of the events on the fiber. The range is not limited to
the fixed ranges provided.
For the manual SmartLoop OTDR test, the maximum range
setting applies to the longest fiber in the pair, including
the loopback and launch/tail fibers. The maximum setting
is 60 km for singlemode.
