• High Input Power Level: 2W
• Wide Wavelength Range: 700nm to 1400nm (MM)

The Keysight 81578A variable optical attenuator is designed for multimode fiber applications and 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:

• Built-in Shutter for Power Meter Zeroing
• Built-in Calibration Capability

Benefits:

• 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.
