Keysight offers a broad choice of fixed laser sources, which are available as single-wavelength and dual-wavelength modules as part of the Keysight Lightwave Solution Platform.

The Keysight 8165xA Fabry-Perot laser sources can be used in conjunction with optical power meter modules for insertion loss, optical return loss, and PDL measurement of broadband components and fiber.

The Keysight 81663A Distributed Feedback Laser Sources are best suited for amplifier test and wavelength division multiplexing (WDM) system test applications. Keysight covers PON and common WDM wavelengths with its 81663A Distributed Feedback (DFB) laser source modules. The precise tunability around ITU-grid center wavelength gives you the flexibility to match test setups to the latest requirements of the dense wavelength division multiplexing (DWDM)-system.

The fine-tuning allows to shift the center wavelength from one DWDM transmission channel to the adjacent channel in dense WDM systems. The built-in isolator ensures highest laser stability, even when reflections are present in the optical path.

Improve Your Productivity With the Right Accessories

External test components such as cables, adapters, and amplifiers represent a critical part and often the weak link in your measurement system. Keysight test accessories improve your productivity, providing accurate and repeatable results, superior RF performance, and unmatched quality and reliability to minimize measurement uncertainty.
