WCaution
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 uses this setting when you do bi-directional
tests. If you select a connector that has a threaded or
bayonet coupler, such as FC or ST, the tester waits for
you to confirm that the connection is complete before it
starts the second part of the test. If you select a quick-
release connector, such as SC or LC, the tester
automatically starts the test when you connect the fiber.
The tester also 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.
No. of
Connectors/
Splices
The Total Connections and Splices settings are applicable
only if the selected test limit uses a calculated limit for loss.
Total Connections: Enter the total number of
connections that are in each path of the link. Do not
adjust the number for the Reference Method you use.
For example, if the link has 3 connections, enter “3” even
if you use the 2 or 3 Jumper reference method. When
the tester calculates the loss limit, it automatically
removes the losses of the connections you used to set the
reference.
