SpaceCONEX 28G 4TRX (100G full duplex)

SpaceCONEX 28G 4TRX (100G full duplex) active blind mate interconnect

The SpaceCONEX28 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.
