Many designers utilize OpenVPX or its general mechanicals for their designs. Combining advanced RF or other device capability into the standard sized modules for the VITA 46/48 architecture is not always practical. To support this trend, Pixus has developed both 19" commercial and rugged rackmount chassis with special card guide trays and deeper card cages. The enclosures support standard 80mm Rear Transition Module (RTM) space on the back side of the backplane as well as customized versions for longer RTMs.
