Agilent / Keysight 83492A Optical clock recovery module

The Agilent/Keysight 83492A Optical Clock Recovery module extracts clock signals from high-speed optical data streams for use in the 86100 family of Infiniium DCA oscilloscopes. This plug-in module integrates clock recovery directly into the measurement platform, eliminating the need for external triggering hardware when working with multimode fiber. It supports a broad wavelength range and multiple standard optical data rates, making it suitable for optical transceiver characterization and optical communication system analysis.
