Step 6: Enter the Wavelength set mode for the OA 5000 by pushing the
WAVELENGTH button so that the top display reads “SEt”.
Step 7: Using the knobs, adjust the wavelength to read 1600 nm.
Step 8: Exit the Wavelength Set mode by pushing the WAVELENGTH
button again; the instrument will require a second to prepare the new
calibration tables (as indicated by the ATT ADJ briefly lighting up).
Step 9: Adjust the OA 5000 such that the display mode is showing
attenuation in dB with the ATT indicator lit and the ---REF indicator not lit.
Step 10: Using the knobs, increase the level of attenuation (turn the
coarse knob clockwise); keep increasing the level until the value reach-
es a maximum level and no longer increases. This value should exceed
50.00 dB.
Step 1: Set the optical power meter as follows (operating instructions
are for HP8153A):
H Select the long wavelength power sensor.
H Wavelength: actual wavelength (±1 nm) of 1310 nm laser
H Averaging: 1 s
Toggle the Mode key to display PARAM, and then press the Param
key to display T and set T to 1 s.
H Displayed units: W (watts)
Step 2: Cover the sensor input and zero the power meter.
Step 3: Connect the 1310 nm laser to the OA 5000 input using the input
fiber specified in the equipment table.
Step 4: Connect the OA 5000 output to the sensor using the output
fiber specified in the equipment table.
NOTE
For the OA 5012, OA 5022, and OA 5032 the input fiber may have a
smaller core diameter than the one specified, as long as the laser
can couple into the fiber. For these models, the output fiber may
have a larger core diameter than the one specified, up to 100
m.
Step 5: Set the OA 5000:
H Wavelength: actual wavelength (±1 nm) of 1310 nm laser
H Attenuation: 0 dB
H Disable: off (unlit)
Shutter Attenuation

button
