The Keysight 8164A Lightwave Mainframe paired with the 81682A Tunable Laser Source delivers a modular platform for optical component characterization across the C-band. The 8164A mainframe accepts one tunable laser source module plus four additional compact optical modules, enabling flexible test configurations. The 81682A provides mode-hop free tuning across 1460 nm to 1580 nm with ±0.01 nm absolute wavelength accuracy and ±0.5 pm repeatability, making it well-suited for DWDM component validation and optical system development.
