The Keysight/Agilent 86115D is a plug-in optical module for the DCA platform family (86100C, 86100D mainframes) engineered for high-volume parallel transceiver testing and waveform analysis. It delivers precise optical signal characterization across Fibre Channel, Ethernet, and OTN standards from 8.5 Gb/s to 100 Gb/s, supporting both early-stage R&D and manufacturing test environments.
