Description

The Keysight 81571A Variable Optical Attenuator provides insertion loss and excellent waviness over a 60 dB attenuation range for characterizing optical network components in telecom and datacom systems.

Features:

• Low PDL, PMD, CD ensure low signal distortion

• Wave flatness: < 0.05 dB

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

• Power meter zero adjustment using built-in shutter

• Built-in calibration function

Benefits:

• High optical performance allows you to test the emitting system and components while ensuring the impact on the input signal.

• The combination of optical performance parameters allows you to flexibly use and reuse the modular attenuator in different setups and applications.

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

• Enhanced internal calibration features reduce uncertainty and improve calibration efficiency for multi-wavelength applications.
