The Keysight 81571A feature excellent wavelength flatness and can handle high input power levels.
The Keysight 81571A variable optical attenuator features lowest insertion loss and excellent wavelength flatness over a complete attenuation range of 60 dB for characterizing optical network components for telecomunication and data communication in systems. Features: Low Signal Distortion due to low PDL PMD CD Wavelength Flatness: < 0.05dB Wide Wavelength Range: 1200nm to 1700nm (SM) Built-in Shutter for Power Meter Zeroing Built-in Calibration Capability Benefits: The high optical performance enables testing of transmission systems and components with minimal impact on the input signal. Unique combination of optical performance parameters gives you the flexibility to use and reuse the modular attenuator in different setups and applications. The integrated shutter protects test equipment and simplifies referencing and power meter zeroing without changes in the setup. Enhanced internal calibration feature reduces uncertainties and speeds up calibration in multi wavelength applications.
