Do the SmartLoop Test
1
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.
2
Make the connections for
End 1
as shown in Figure 157.
Notes
To decrease the wear on the OTDR connector and
help keep it clean, use an OTDR port protector
(30 cm, 12 in) patch cord to connect the OTDR to the
launch and tail cords for bi-directional SmartLoop
tests.These cords are available from Fluke Networks.
To minimize the effect of the port protector patch
cord on results, do not use a cord longer than 50 cm
(20 in).

Halfway through the test, the tester tells you to connect the
tail cord to the OTDR port. Make the connections for
End 2
as
shown in Figure 157, then tap
DONE
.
The tester automatically calculates bi-directional averages of loss
measurements. See “Averaged Bi-directional Results” on
page 388.

Caution
Switch the launch and tail connections at the end of
the short patch cord. If you switch the connectors at
the patch panel, you will possibly get less accurate
results for those connections during the second half
of the test.

If
Auto Save
is on, the tester uses the next two IDs to save the
results for the two fibers.
If
Auto Save
is off, and you tap
SAVE
or
FIX LATER
, the
SAVE
RESULTS
screen shows the next two IDs available. You can
change the IDs if necessary.
