The component base under all six

Every position above buys the same two families: UQD panel-mount couplings and UQDB blind-mate couplings, with rack manifolds in EIA 42U–52U or the ORv3 rack standard. Port pitch and interface size are what change between links; the interface standard does not. designed to the OCP UQD/UQDB specification
