Revolutionary Active Blind Mate Optical Interconnect for Space VPX Systems

PublishTime： 2021-04-28 Article Source：Smiths Interconnect

The SpaceCONEX™28 revolutionary active blind mate optical interconnect for Space VPX systems, consists of a plug-in module connector and a backplane connector compatible with the forthcoming VITA 66.5 standard. A SpaceCONEX28 SC optical transceiver is directly integrated into the plug-in module connector, saving board space and eliminating fiber cable handling.

The backplane connector is VITA 66.5 backplane cut-out compatible and includes a spring to ensure a secure MT to MT mating connection under extreme shock and vibration conditions.
