description
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.
characteristic:
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
Advantage:
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.
