81571A Optical attenuator module

Functional Features Attenuation Range: 0 dB to 60 dB Maximum Input Power: 2 W Wavelength Flatness: < 0.05 dB High Attenuation Accuracy: < 0.1 dB Repeatability: < 10 mdB Broad Wavelength Range: 1200 nm to 1700 nm (single-mode) Low PDL, PMD and CD for minimal signal distortion Built-in shutter enables power meter zeroing On-board calibration function available Advantages Superior optical communication performance facilitates testing of transmission systems and components with negligible impact on input signals. The unique combination of optical performance parameters allows flexible deployment and reuse of the modular attenuator across diverse configurations and applications. The integrated shutter protects test equipment and simplifies reference measurement and power meter zeroing without configuration modifications. Enhanced internal calibration reduces measurement uncertainty and accelerates calibration for multi-wavelength applications.
