The JDS Uniphase JDSU HA9 HA097+21KFP1 is a programmable optical attenuator that delivers precise, fine-grained control of optical signal strength across telecommunications, fiber optic test, and laboratory applications. Operating across single-mode fiber, this instrument provides attenuation up to 100 dB with 0.01 dB resolution and ±0.03 dB typical accuracy. Front-panel keypad control, GPIB (IEEE 488.2), and RS232 interfaces with SCPI/HP8156A command compatibility enable flexible integration into automated test systems. Low insertion loss, high return loss exceeding 60 dB, and minimal polarization-dependent loss preserve signal integrity across demanding measurement scenarios.
