Chapter 7: Use the OTDR
The SmartLoop Test


To switch between results for fibers A and B, tap on the
EventMap screen.
If you did a bi-directional SmartLoop test, touch for 3
seconds to see a summary of the results from ends 1 and 2 on
fibers A and B. To see the EventMap for a result in the list, tap
the result.
Note
When you save SmartLoop results, the tester saves
the results in two records, one for each fiber in
the link.
Bi-Directional SmartLoop Tests
OTDR tests from both ends of a fiber can give different results
because the properties of fibers are not always the same in both
directions. The differences can cause differences in the loss
measurements in each direction. For this reason, bi-directional
results are frequently included in the requirements for jobs.
The bi-directional SmartLoop test gives you bi-directional OTDR
results for both fibers in a link. If necessary, you can use the bi-
directional averaging function in LinkWare PC software to get the
average loss for both directions.
To do a bi-directional SmartLoop test
1
On the home screen, tap the test setup panel, make sure the
correct SmartLoop test is selected on the
CHANGE TEST
screen,
then tap
EDIT
.
2
On the
TEST SETUP
screen, in the
Bi-Directional
panel, tap the
control to make it show
On
, then tap
SAVE
.
3
On the home screen, make sure the IDs for the fibers are
correct. The tester uses the
Fiber A
ID for the fiber connected
to the launch cord at the start of the test.
