Appendix C: Loss Test Methods for Fiber Cabling
Introduction
Notes
The following discussion uses the 1, 2, and 3
jumper terminology for the names of the three
common test methods. See Appendix B for a cross-
reference of the method names in various
standards.
ANSI/TIA/EIA-526-14A and 526-7 specify Method B
for measuring loss on multimode premises fiber
and Method A.1 for singlemode premises fiber,
respectively. Both are 1 Jumper methods.
The number of fiber connections represented in loss test
results depends on the method used for making reference
and test connections. This appendix describes the three
common methods, 1, 2, and 3 jumper.
To test links with different connectors at each end, visit the
Fluke Networks Knowledge Base for suggestions.
Use the Test Method setting on the tester’s Fiber menu in
SETUP to record the method used. This setting does not
affect loss results. It is only saved with the results to record
which method you used.
