Electrical Specification
VPX
While no specific node-to-node interconnection method is specified in JAS it is highly recommended that the nodes make use of a standards-based chassis and backplane such as VPX defined by VITA. The VPX standard provides high-speed switched serial interconnects between plug-in modules or nodes while providing for parallel bus interconnects as well as additional I/O capability at the plug-in module level. It is based upon the 6U and 3U Eurocard format of plug-in modules and defines a high-speed connector family for use with these modules. Photographs of a VPX chassis and plug-in module are shown below.
