OPM Used RP 460
OLS Used DLS 355
The fiber-under-test is paired singlemode
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
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 singlemode
loopback adapter. It should be blue and have a
duplex bulkhead on the end.
The RP 460 power meter is set to the
1550nm wavelength. The 1310nm
wavelength may also be used. Always
match the wavelength on the RP 460
to the wavelength on the DLS 355. The
adapter on the RP 460 is the AC 029 LC
adapter.
The DLS 355 laser source is set to the
1550nm wavelength. The 1310nm
wavelength may also be used. The
adapter is the default AC 022B SC adapter.

The fiber-under-test is singlemode with 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.
The test jumper is a one-meter singlemode fiber
with SC and LC connectors. The SC connector will
be plugged into the DLS 355 laser source and the
LC connector will be used to interface with the
fiber-under-test.
The RP 460 power meter is set to the
1550nm wavelength. The 1310nm
wavelength may also be used. Always
match the wavelength on the RP 460

should be blue and have a duplex bulkhead on the end.
POWER METER
The OPM1 power meter is set to the 1550nm
wavelength. The 1310nm wavelength may also be
used. Always match the wavelength on the OPM1 to
the wavelength on the LSSM. The adapter on the OPM1
is the OPAL LC adapter.
LIGHT SOURCE
The LSSM laser source is set to the 1550nm
wavelength. The 1310nm wavelength may also be used.
The adapter is the default OPAS SC adapter.
