The JDS Uniphase HA9-Z040 is an extended range programmable optical attenuator delivering precise attenuation control across the C and L bands. It provides 0 to 100 dB attenuation with 0.01 dB resolution and repeatability, supporting wavelengths from 1200 nm to 1700 nm. The unit achieves ±0.1 dB accuracy and maintains wavelength dependence below ±0.05 dB across the 1530–1625 nm range, making it ideal for power meter testing, linearity calibration, fiber link loss simulation, and bit error rate measurements.
