4 On the TEST SETUP screen, in the Bi-directional panel, tap the
control to make it show On, then tap SAVE.
5 Do an Autotest.
6 Halfway through the test, the tester tells you to switch the
input and output fibers. Connect to the link as shown on the
right side of Figure 123.
WCaution
Switch the connections at both ends of the patch
panel or fiber under test, not at the tester's and
remote’s ports. If you disconnect a test reference
cord from an output port on the tester or remote,
the reference value will be unreliable.
Note
The directions Main>Remote (main to remote)
and Remote>Main (remote to main) in the bi-
directional results are only the directions of the
optical signals for the second half of the test. If a
fiber fails, the direction does not tell you the
location of the problem.
7 If Auto Save is on and the tester is in Smart Remote mode, the
tester uses the next two IDs to save the results for the two
fibers.
If Auto Save is off, the SAVE RESULT screen shows the next two
IDs available. You can change the IDs if necessary.
