180
This chapter explains how to use the Agilent 8163A/B Lightwave
Multimeter, Agilent 8164A/B Lightwave Measurement System, or
Agilent 8166A/B Lightwave Multichannel System together with the
8156xA/8157xA family of Variable Optical Attenuator modules to
attenuate and control optical power in single-mode optical fibers.
Here you will find:
• A brief description of the modular Agilent 8156xA/8157xA Variable
Optical Attenuator family,
• A description of how to use these modules, including applying an
attenuation factor, setting an output power, applying offset factors,
constructing a λ offset table, and (for the 81566A, 81567A, 81576A,
and 81577A) using the power control feature.
