Example 1: Singlemode Fiber, Point-to-Point, 1 Jumper
Fiber Type Singlemode
Connectors Used LC
Test Jumper Setup Single
OPM Used RP 460
OLS Used DLS 355
Fiber-Under-Test
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.
Test Jumper
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.
Power Meter
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.
Light Source
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.
400m Fiber
1m Jumper
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.
