The Keysight Z2002-86142 is a Network Expansion System component for the 86142B Optical Spectrum Analyzer, a benchtop instrument engineered for high-precision spectral analysis in WDM component and system testing. This OSA delivers exceptional wavelength and power accuracy, dynamic range, and low polarization dependency for demanding optical network applications.
Technical Specifications
The analyzer operates across the 600 nm to 1700 nm wavelength range, covering S, C, and L bands. Wavelength accuracy reaches 10 pm with user calibration, while reproducibility maintains ± 0.002 nm with a 9/125 µm input fiber over ≤ 1 minute intervals. The span range extends from 0.2 nm to full range with zero span capability.
Sensitivity is defined as signal values exceeding 6 × RMS noise. Absolute accuracy applies for resolution ≥ 0.1 nm with 9/125 µm fiber. Polarization dependence specifications apply at resolution ≥ 0.2 nm, room temperature, and 9/125 µm fiber. Operating conditions specify 0 °C to 55 °C ambient temperature and relative humidity < 95%, after one hour stabilization and auto-align execution.
Flatness defines the floating-band amplitude error across the specified wavelength range and can be corrected through user amplitude calibration. Scale fidelity addresses amplitude readout linearity at points other than the calibration reference.
