Step 1: Disconnectthe fibers from the OA 5000, 1550 nm laser,and
long wavelength sensor.Connect the 850 nm laser to the input fiber and
the short wavelength sensor to the outputfiber. Connect the fibers
together using an FC/FC adapter.Set the laser to CW (unmodulated)
mode, and set the laser power level (ifadj ustable)to maximum, but not
more than 2 mW.Turn on the laser.
Step 2: Atthe power meter, select the short wavelength sensor.Set the
wavelength displays ofthe OA 5000 and the power meter to the actual
wavelength (not the nominalw avelength)of the laser, within ±1 nm.
Step 3: Setthe power meter to W (watts) mode. The reading should be
at least 400 W.Set the power meter to dB relative (dB key) mode, and
set the dB reference (Disp-->Ref). The power meter should read 0.0 dB
±0.1 dB.
Step 4: Disconnectthe fibers from the FC/FC adapter,and connect
them to the OA 5000.
Step 5: Setthe OA 5000 attenuation to 0 dB, and the DISABLEbutton
to off (unlit).
Step 6: Thepower meter reading is the insertion loss of the OA 5000.
Check that the power meter reading is ---4.0dB or higher (more posi-
tive).

During theremaining steps, do not disturbthe connections and
fibers.
