About APC Connectors
When you do tests on links with APC (angled physical contact)
connectors, use only test reference cords with APC connectors on
the ends connected to the link. If you connect non-APC
connectors to the link, the connectors will cause large reflections
that make loss measurements inaccurate.
For tests on links with APC connectors, use test reference cords
that also have APC connectors on the ends connected to the
tester’s input ports. This is necessary for the 1 jumper reference
method. You can connect APC connectors to the tester’s input
ports because the fiber does not touch the lens on the input port.
WCaution
Do not connect APC connectors to the output ports.
Doing so can damage the port’s UPC endface and
cause unreliable test results.
Figure 57 shows the TRCs necessary for tests on links with APC
connectors.
