About 1 Jumper Connections

The reference and test connections shown in this manual
produce 1 Jumper results. 1 Jumper results include the loss
of the fiber plus the loss of the connections at both ends of
the link. To ensure accurate results, the connection to the
fiber module's output port must not be disconnected after
the reference is set. Using connector adapters that match
the connectors in the fiber under test lets you connect to
the fiber without disturbing the output port connection.
If you disconnect the test reference cords from
the tester's or smart remote's output port after
setting the reference, you must set the
reference again to ensure valid measurements.
If you do not have the correct connector adapters, see
Appendix C, "Modified 1 Jumper Method" for alternative
connections that produce 1 Jumper results.
To test links with different connectors at each end, see the
alternate method described in the Appendix of the DTX
Series CableAnalyzer Technical Reference Handbook or
visit the Fluke Networks Knowledge Base for suggestions.

Caution

Certifying Fiber Cabling

The Autotest runs the tests required to certify that fiber
cabling meets a particular standard. You run the Autotest
in Smart Remote, Loopback, or Far End Source mode,
depending on whether you are testing duplex cabling,
spools, test reference cords, or single-fiber cabling.

Autotest in Smart Remote Mode

Use Smart Remote mode to test and certify dual-fiber
cabling. In this mode, the tester measures loss, length, and
propagation delay on two fibers at two wavelengths in
one or both directions.
Figure 7 shows the equipment required for testing fiber in
Smart Remote mode.
