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’spower
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.
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).
