The Keysight 86115D is a dual-channel 20/34 GHz optical receiver module engineered for high-volume parallel testing of optical transceivers. This module delivers wide bandwidth and low-noise performance across the 750 to 1650 nm wavelength range, with calibrated optical-to-electrical conversion gains at 850 nm, 1310 nm, and 1550 nm. It integrates with the Keysight 86100D DCA-X mainframe to enable rapid characterization of optical components in manufacturing environments.
