OA 5000 Series User Manual 1 --- 3
A Quick TourThis section providesa brief overview of the OA 5000 Optical Attenuator. The
overview illustrates how easy it is to learn about and use the OA 5000.
Youcan read this section or you can choose to investigate the OA 5000 on
your own. If you decide not to read the overview, refer to the User Reference
section to answer any questions you may have. User Reference also de-
scribes details and features notcovered in this section.
In this section youwill set up the OA 5000 and change various settings to
show get a feel for how the OA 5000 works. Youwill not be using any optical
signals.
Figure 1-2, on page 1---4,presents a front panel view of the OA 5000.
If you have not alreadydone so, install the OA 5000 as described on
page 1---1and turn on the instrument.
Step 1: Press MODEso that the ATT indicator is lit and -- R EF isnot lit.
This sets the OA 5000 to displayattenuation in absolute units rather than
displayingattenuation relative to a reference value.
Step 2: Press WAVELENGTH. The word SET will appear in the attenua-
tion display.
Step 3: Using the COARSE and FINE knobs, set the WAVELENGTH to
1300 nm.
The actual attenuation ofan optical input signal varies depending on the
wavelength of the signal. Toensure accurate attenuation readings, set
WAVELENGTH to the wavelength of the signal you are attenuating.
Step 4: Press WAVELENGTH again to accept the new wavelength
value.
Step 5: Press DISABLE,sothatitisnotlit.
If the DISABLEbutton is lit, the shutter inside the OA 5000 blocks the
signal path, providing ≥100 dB attenuation forthe OA 5002, OA 5012,
and OA 5022, and ≥90 dB attenuation for the OA5032. When the
DISABLEbutton is not lit, the shutter is withdrawn from the optical
signal path, enabling youto set the attenuation value from 0 to 60 dB in
0.01 dB increments.
Step 6: Press MIN ATT.
This sets the OA 5000 to 0 dB attenuation.
