Reference
Method On the No. of Connectors/Splices screen, set the number
of jumpers you will use in each fiber path when you set
the reference. The dotted lines in the diagram on the
screen show you which parts of the link are included in
the test results.
The number of jumpers you use has these effects on loss
measurements:
1 Jumper: Loss measurements include the connections at
both ends of the link. The figures in this manual show 1
Jumper connections.
2 Jumper: Loss measurements include one connection at
one end of the link.
3 Jumper: Loss measurements do not include the
connections at the ends of the link. The tester measures
only the loss of the fiber.
This setting does not change the loss measurements, but
it can change the PASS/FAIL result for test limits that use
a calculated loss limit. For all test limits, the tester saves
this setting to show the reference method you used.

Caution
Most cable manufacturers will give you a
warranty on a fiber installation only if you use
the 1 Jumper reference method when you
certify the installation.
Note
Different standards use different names for the
three methods. See Appendix B. For more
information about the methods, see
Connector Type Select the type of connector, such as SC or LC, used in the
cabling. The tester saves this setting to record the type of
connector you used. This setting does not change your
test results or any of the diagrams that the tester shows.
If the correct type is not in the list, select General.
