JDS Uniphase JDSU HA9 HA97E+18KFA1 Programmable Attenuator

The JDS Uniphase JDSU HA9 HA97E+18KFA1 is a programmable optical attenuator delivering precise control of optical signal power across extended attenuation ranges. Operating from 1200 to 1700 nm (optional 750–1700 nm), this instrument provides 0 to 100 dB attenuation with 0.01 dB resolution and ±0.03 dB typical accuracy. Designed for test labs, system characterization, and demanding measurement environments, it combines high repeatability with low insertion loss and exceptional return loss performance.
