81571A Variable Optical Attenuator Module with Angled Interface

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.

• High Input Power Level: 2W
• Wavelength Flatness: < 0.05dB
• High Attenuation Accuracy < 0.1dB
• Repeatability < 10mdB
