Home Shop Wireless Design and Test RF Signal Conditioning PXI Optical Attenuator

PXI Optical Attenuator

Reduces the power level of an optical signal used in a production test environment.

The PXI Optical Attenuator provides two channels of variable optical attenuation (VOA) for broadband wavelengths. You can precisely control the individual attenuators using the included driver software. It offers single-mode fibers and SC/PC connectors. The PXI Optical Attenuator is ideal for reliable testing in continuous production environments.
