The MN9625A/9626A Programmable Optical Attenuators have excellent attenuation performance. They are calibrated with a high- ccuracy calibration system over an attenuation range of 0 to 60dB.

The MN9625A has a superior wavelength flatness of 0.2dBp-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.

Features:

• Attenuation accuracy of +/-0.05dB (typical)
• Wavelength flatness of 0.1dBp-p (typical, 1.52 to 1.57 m, MN9625A)
• Low polarization dependant loss of 0.05dBp-p max. (MN9625A)
• Return loss of 45dB min. (PC connector) and 60dB min. (APC: Angled PC connector)
• Removable optical connector for easy cleaning and replacement
