LightCONEX28 LC 100G

LightCONEX28 LC revolutionary active blind mate optical interconnect for VPX systems.

LightCONEX28 100G active blind mate optical interconnect

The LightCONEX28 LC revolutionary active blind mate optical interconnect for VPX systems, consists of a plug-in module connector and a backplane connector compatible with the forthcoming VITA 66.5 standard. A LightCONEX28 optical transceiver is directly integrated into the plug-in module connector, saving board space and eliminating fiber cable handling. The backplane connector is VITA 66.4 backplane cut-out compatible and includes springs to ensure a secure MT to MT mating connection under extreme shock and vibration conditions.
The LightCONEX28 LC is offered with a (4+4)-lane transceiver in industrial operating temperature. Each lane operates at up to 28 Gbps.

The LightCONEX28 blind mate optical interconnect for VPX embedded computing systems, consists of a module connector and a backplane connector compatible with the VITA 66.4 standard.

The LightCONEX28 solution frees up board space by integrating the optical transceiver into the board edge connector. The backplane connector, also part of the LightCONEX28 solution, has a spring-loaded mechanism ensuring optimal optical mating meeting VITA 66.0 requirements. The rugged construction of these connectors ensures error free data transmission under severe shock, vibration, and temperature extremes.
