Optical Attenuator

The 81560A and 81561A are small and cost effective attenuator modules with high resolution. The Keysight 81566A and 81567A feature power control functionality that allows setting the output power level directly. When the power control mode is enabled, the module automatically corrects power changes at the input to maintain the output level set by the user.Features：High input powers up to 2 WattExcellent wavelength flatness: typical ± 0.05 dBLow insertion loss: typical 0.7 dBWide wavelength range: 1200 nm to 1700 nm (SM), 700 nm to 1400 nm (MM)High resolution: 0.001 dBModular design allows up to 17 attenuators in one mainframeActive power control options to set power levels directlyComprehensive offsets allow easy calibration of the set-upIntegrated shutterThe Keysight versatile optical connector interfaces for all
