No. : 81570A
Brand : Keysight

Main characteristics and technical indicators

High input power level: 2 W

Wavelength flatness: < 0.05dB

High attenuation accuracy < 0.1dB

Repeatability < 10mdB


The Keysight 81570A variable optical attenuator provides the lowest insertion loss and excellent wavelength flatness in the 60 dB attenuation range, characterization of optical network components in telecom and datacom systems.


Low PDL, PMD, CD ensures low signal distortion

Wavelength flatness: < 0.05dB

Wide wavelength range: 1200 nm to 1700 nm (SM)

Power meter zero adjustment using built-in shutter

Built-in calibration


Higher optical performance allows you to test your transmitter system and components while minimizing the impact on the input signal.

The unique combination of light performance parameters allows you to flexibly use and reuse modular attenuators in different settings and applications.

The integrated shutter protects the test equipment and simplifies positioning and power meter zero adjustment (without having to change settings).

Enhanced internal calibration features reduce uncertainty in multi-wavelength applications and increase calibration efficiency.
