Laser should have short coherence length (<1 m if possible) and multiple longitudinal
modes to minimize effects of polarization and reflection. If a DFB or tunable laser is used, it
should have a coherence control feature and optionally a polarization scrambler.

The fiber specifications assume that adapters on the test equipment and the DUT (device
under test) are FC/PC. Alternative adapters can be used with appropriate changes in the
fiber connectors.

Step 1: Insert the OA 5000 into a powered-down Tektronix TM 5000
series Mainframe power supply.
H Make certain that the OA 5000 is securely latched into the main-
frame.
Step 2: Turn the TM 5000 mainframe power on (via mainframe’s power
switch)
Step 3: A few seconds are required after mainframe power-up before
the OA 5000 displays become lit.
H Once the displays become active, all LEDs and digital segments will
be lit for a couple of seconds; any segment which does not light up
during this time is either defective, burnt out, or is not connected.
during this time is either defective, burnt out, or is not connected.
H This test can be invoked anytime after power up by pushing and
holding the ADDR(SET) button.
Step 4: The wavelength, attenuation, and display mode will power-up at
whatever values existed before the previous power-down; if the instru-
ment is being powered on for the first time the settings will be at their
factory default values (see manual for these default values).
