The MN9625A/9626A Programmable Optical Attenuator
has excellent attenuation accuracy. It is calibrated with a
high-accuracy calibration system over an attenuation
range of 0 to 60 dB.
The MN9625A has a superior wavelength flatness of 0.2
dBp-p max. by using an attenuation element with very flat
wavelength characteristics. It is the ideal instrument for
evaluating WDM (wavelength division multiplexing) optical
amplifiers in which gain flatness vs. wavelength is an
important factor. Moreover, the MN9626A has a built-in
optical monitor output for monitoring the level of through
light.
