The JDS Uniphase JDSU HA9 HA097+20ASU1 is a high-resolution programmable optical attenuator delivering precise signal control across the extended C-band and L-band wavelength ranges. This instrument provides 0 to 100 dB attenuation with 0.01 dB resolution and repeatability, enabling deterministic optical power management in laboratory and production test environments. The attenuator’s inherently linear response, combined with built-in calibration and offset functions, allows direct display matching to external optical power meters across a broad dynamic range.
