VPX Optical Interconnects

The LightCONEX® series of optical plug-in and backplane module connectors for VPX systems is Smiths Interconnects’ answer to the stringent SWaP requirements of today’s Defense applications in which fiber optics are replacing high bandwidth coaxial copper interconnects. 

This VPX series of active, blind mate optical interconnects solution offers flexibility, light weight, very high bandwidth, and forward compatibility. The LightCONEX active blind mate optical interconnect is a revolutionary solution for VPX systems that includes a fixed plug-in module connector and a floating backplane connector compatible with proposed VITA 66.5 standard. The low-profile plug-in module connector is screwed on the board edge through an interposer, saving board space and eliminating fiber cable handling. The backplane connector has a spring-loaded mechanical transfer (MT) ferrule to ensure a secure MT to MT mating connection under extreme shock and vibration conditions.

SpaceCONEX28 SC 100G (full duplex)

The SpaceCONEX28 SC 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. SpaceCONEX28 SC optical transceiver is directly integrated into the plug-in module connector, saving board space and eliminating fiber cable handling.


The LightCONEX® optical backplane module connector consists of a connector shell and insert. The shell is designed to provide float for the insert in both the X- and Y-directions to enable alignment of the MT ferrule mating interfaces. The design complies with the ANSI/VITA 66.4 mating requirements with the MT ferrule displacement occurring within the backplane connector.
