About Method B Connections
The reference and test connections shown in this manual
produce Method B results. Method B 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.
WCaution
If you disconnect the reference test 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 B, "Modified Method B" for alternative
connections that produce Method B 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.
