The VIAVI Solutions HA017+20AFA1 is a programmable optical attenuator for precise control of optical signal power in laboratory and manufacturing environments. It delivers accurate, repeatable attenuation across the 1200–1650 nm band with minimal signal degradation. The instrument supports computer-based control via USB, Ethernet, and GPIB interfaces, enabling automated test sequences and calibration workflows. Its low insertion loss and high return loss characteristics ensure signal integrity in critical optical power management applications.
