Bi-Directional Testing
You can test cabling in both directions and save the bi-
directional test results in all test modes.
Bi-Directional Testing in Smart Remote or
Loopback Mode
1 On the main tester’s Job tab in Setup, enter names for
END 1 and END 2 to identify the ends of the cabling.
Name END 1 as the end where the main tester will be
located.
2 Set THIS END to END 1.
3 On the main tester's Loss/Length tab, set
BI-DIRECTIONAL to Enabled.
4 Run a loss/length test on the cabling. Halfway through
the test, the tester prompts you to swap the fibers at
each end of the cabling. Swap the connections at the
patch panel, not at the tester's ports.
5 Press
s
to save the test.
Bi-Directional Testing in Far End Source Mode
1 On the Job tab in Setup, enter names for END 1 and
END 2 to identify the ends of the cabling. Name END 1
as the end you will test first.
2 Set THIS END to END 1.
3 Test all the cabling and save the results from END 1.
4 On the Job tab, change THIS END to END 2; then test all
the cabling from the other end. When you save each
result, use the same fiber ID you used for the results
from the first end. The used IDs will be in the IDs IN
CURRENT FOLDER list.
Diagnosing Loss/Length Test Failures
Table 7-10 describes some typical causes of loss/length test
failures.
See also the table in Appendix C, which shows results from
a survey on common causes of fiber link failures.
