Highlights

The Keysight 81570A 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:

  • Attenuation Range: 0dB to 60dB
  • High Input Power Level: 2W
  • Wavelength Flatness: < 0.05dB
  • High Attenuation Accuracy < 0.1dB
  • Repeatability < 10mdB
  • Low Signal Distortion due to low PDL, PMD, CD
  • 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
