The JDS Uniphase HA97E-19KSC1 is a programmable optical attenuator delivering precise control of optical signal power across telecommunications, data networking, and laboratory environments. Part of the HA9 Series, this instrument combines extended attenuation range with high resolution and repeatability, making it essential for power meter calibration, component characterization, and system validation where accurate attenuation control is critical.
## Technical Specifications
• **Attenuation Range:** Extended range up to 100 dB
• **Resolution:** 0.01 dB nominal
• **Repeatability:** ±0.01 dB
• **Accuracy:** ±0.1 dB typical (±0.15 dB in some configurations; accuracy varies outside calibrated wavelength ranges)
• **Wavelength Range:** 1200–1700 nm standard; 750–1700 nm available for specific models
• **Wavelength Dependence:** <±0.05 dB over 1530–1625 nm
