  • Avionics Data Loaders

    Astronics Corporation

    The Ballard DL 615 Data Loader is the modern replacement for outmoded 3½-inch floppy-disk-only ARINC 615 portable data loaders (PDL). Any PC running Microsoft® Windows® can perform data loads using the USB to ARINC 429 interface, cables, and software included with the DL 615. While being as simple to use as older floppy disk PDLs, the DL 615 provides record keeping, flexibility in data management, and powerful features for troubleshooting and enabling data loads into difficult LRUs. As an added benefit, the interface can be used as a general purpose ARINC 429 (and optionally ARINC 717) maintenance tool.

  • Fixed Laser Source Module

    Keysight Technologies

    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 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 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.
