The JDS Uniphase HA097+28ASC1 is a programmable optical attenuator for precise signal level control across telecommunications and data communication test environments. This benchtop instrument delivers attenuation across a 100 dB range with 0.01 dB resolution, supporting single-mode 9/125 µm fiber from 1200 nm to 1700 nm. It combines front panel keypad control with GPIB and RS232 interfaces, accepting SCPI/HP8156A command sets for integration into automated test systems.

## Compatibility & Integration
The attenuator operates via front panel keypad, GPIB (IEEE 488.2), or RS232 serial control. It accepts standard 10/90, 50/50, 2/98, and 30/70 coupler configurations for application-specific optical splitting requirements. SCPI/HP8156A command compatibility enables direct integration into existing test automation frameworks.
