FIBER-UNDER-TEST
The fiber-under-test is paired multimode with paired
LC connectors on each end. The fiber-under-test may
be up to 250 kilometers long. In this example, the
fiber-under-test is 400 meters long.
TEST JUMPER
The test jumper is paired for loopback testing. One end
has an SC connector and an LC connector, and the other
end has two LC connectors clipped together. This
method also uses a multimode loopback adapter. It
should be black and have a duplex bulkhead on the end.
POWER METER
The OPM1 power meter is set to the 850nm
wavelength. The 1300nm wavelength may also be
used. Always match the wavelength on the OPM1 to the
wavelength on the LSMM. The adapter on the OPM1 is
the OPAL LC adapter.
LIGHT SOURCE
The LSMM LED source is set to the 850nm
wavelength. The 1300nm wavelength may also be used.
The adapter is the default OPAS SC adapter.
