Overview

The Keysight 81570A variable optical attenuator provides ultra-low insertion loss and excellent wavelength flatness over a full 60 dB attenuation range for characterizing optical network components in telecom and datacom systems.

Features:

• Attenuation range: 0 dB to 60 dB
• High input power level: 2W
• Wavelength flatness: < 0.05dB
• High attenuation accuracy: < 0.1 dB
• Repeatability: < 10 mdB
• Low PDL, PMD, CD to ensure low signal distortion
• Wide wavelength range: 1200 nm to 1700 nm (single mode)
• Built-in shutter provides power meter zeroing capability
• Built-in calibration function

Advantages:

• Excellent optical performance with minimal impact on input signals, allowing more accurate testing of transmission systems and components
• Unique combination of optical performance parameters allows you to use modular attenuators flexibly and repeatedly in a variety of settings and applications
• Integrated shutter protects test equipment and simplifies positioning and zeroing of power meters (without changing setup)
• Enhanced internal calibration capabilities reduce uncertainty in multi-wavelength applications and improve calibration efficiency
