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 for modified Method B and alternative
connections that produce Method B results.
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 7-8 shows the equipment required for testing fiber
in Smart Remote mode.
