VPX optical interconnects

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 MT to ensure a secure MT to MT mating connection under extreme shock and vibration conditions.

Backplane connector

The LightCONEX backplane connector contains the Face plate and Insert. The connector is designed to provide float 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.
Single or dual MT ferrules and/or hybrid configurations (including RF coaxial contacts) are available.

Face Plates

Different backplane face plates are available to accommodate VITA apertures:

Inserts

The face plate styles mate with insert styles. The inserts come with the required MT-terminated optical cable(s) and MT ferule(s). Compatibility is shown in above diagram:

Backplane connector features

  • Spring-loaded MT ferrule (12-lane or 24-lane)
  • Coarse and fine mating alignment
  • Low profile: 10 mm height
  • Compatible with 12-lane or 24-lane OM3 or OM4 fiber ribbon cable

The main components of the backplane connector are:

  1. Face plates. Dedicated face plates are available for VITA 67.3 (apertures C, D, and E) and VITA 66.4.
  2. Insert housing available in styles A, B, C, and Crf. The main components of the housing are:
  3. Primary alignment feature
  4. MT ferrule with alignment pins
  5. Optical cable assembly with springs

Plug-in module connector

The LightCONEX plug-in module connector contains the optical transceiver with its MT ferrule, an LGA interposer, and a front mating plate. The front mating plate has the primary alignment feature socket and a hole to accommodate the MT from the transceiver.
