The JDS Uniphase HA027+20ASU1 is a programmable optical attenuator that delivers precise, stable reduction of optical signal power across telecommunications and test wavelengths. It combines a wide 100 dB attenuation range with 0.01 dB resolution and ±0.1 dB accuracy, making it suitable for power meter calibration, BER testing, system characterization, and laboratory measurements where signal level control must be both accurate and repeatable.
