LightCONEX blind mate optical interconnect for VPX embedded computers

LightCONEX 40 Gbps and 120 Gbps blind mate optic

The LightCONEX™ revolutionary 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. A LightABLE 40G optical transceiver is directly integrated into the plug-in module connector, saving board space and eliminating fiber cable handling. The backplane connector is a low profile drop-in replacement for the VITA standard but includes springs to ensure a secure MT to MT mating connection under extreme shock and vibration.
The LightCONEX is offered with 12-lane transmitters, a 12-lane receivers, or (4+4)-lane transceivers in commercial, extended, or industrial operating temperatures. Each lane operates at up to 10 Gbps.
