4 Select three launch cords that have the same type of fiber as
the fiber you will test. The connectors must be the correct
type for each connection you will make. If necessary, you can
connect two launch cords together to make a loopback cord
that has the same connectors on both ends.
5 On the home screen, tap SET COMP.
6 On the SET LAUNCH METHOD screen tap SmartLoop.
7 Clean and inspect the OTDR port and connectors on the three
launch cords.
8 Make the connections shown in Figure 183 on page 469.
9 Tap SET.
10 When the SET LAUNCH COMP screen shows, make sure the
tester shows the correct distances for the end of the launch
cord and the start of the tail cord.
Note
If the fibers have APC connectors, the tester
possibly will not find the correct launch and tail
events. If this occurs, do the compensation again
and select Manual Entry to enter the lengths of
the cords manually.
11 Tap SAVE.
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 186.
