Smiths Interconnect has released LightCONEX optical plug-in and backplane modules.

These connectors are compatible with the VITA 66.5 draft standard and are aligned with the SOSA Technical Standard for VPX systems within rugged embedded computing applications and sensor systems.

The Sensor Open Systems Architecture (SOSA) Consortium is developing a common framework for transitioning sensor systems to an open systems architecture, based on key interfaces and open standards established by industry-government consensus.

Smiths Interconnect has been heavily involved in the VITA 66.5 standard development under OpenVPX and is an active member of the SOSA consortium, which references the VITA 66.5 draft standard.

The LightCONEX active blind-mate optical interconnect system incorporates an optical transceiver into the plug-in module connector. The interconnect meets military standard requirements for shock, vibration, and harsh environmental conditions.

The LightCONEX system includes a fixed plug-in connector and a floating backplane connector compatible with the VITA 66.5 standard. The low-profile plug-in transceiver connector is screw-mounted on the board edge through an electrical interposer, saving board space and eliminating fibre cable handling. The backplane connector has a spring-loaded MT to ensure a secure MT to MT mating connection under extreme shock and vibration conditions.

LightCONEX VPX optical interconnects offers the following benefits:

  • Increased volumetric density by incorporating 10G or 25G edge-mounted transceivers into the plug-in interconnect
  • Port bandwidth density of up to 700 Gbps full-duplex in a half-width aperture
  • Easy VPX board assembly and rework by eliminating fibre pigtail on edge-mount transceiver
  • Rugged interconnects capable of 500 mating cycles and qualified to MIL-STD-1344A for shock and vibration
