description
The Keysight 81578A variable optical attenuator is specifically designed for multimode fiber applications, providing the lowest insertion loss and excellent wavelength flatness in the 60 dB attenuation range, and characterizing optical network components for telecommunications and data communications systems.
characteristic:
Zero adjustment of power meter with built-in shutter
Built-in calibration function
Advantage:
The integrated shutter protects the test equipment and simplifies positioning and zero adjustment of the power meter (without changing settings).
Enhanced internal calibration features reduce uncertainty in multi-wavelength applications and increase calibration efficiency.
