The Tektronix OA5002 is an optical attenuator module designed for precise characterization and calibration of optical systems across the telecommunications and datacom spectrum. Operating as a plug-in accessory for TM5000 series mainframes, it delivers variable attenuation with exceptional accuracy and repeatability for receiver sensitivity analysis, fiber optic equipment development, and standards-based testing including SDH/SONET, Fibre Channel, and Ethernet applications.
