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
with 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.
Connect only UPC connectors to the tester's output ports.
