Provided is a process for the manufacture of a mineral-insulated socket, especially as a module for the manufacture of an electrical feedthrough and especially for use in an exhaust gas duct of a motor vehicle. The mineral-insulated socket has a metallic inner part arranged in a metallic outer pipe and electrically insulated from this metallic outer pipe by an electrically insulating, mineral material. In a process, the metallic inner part, the electrically insulating material, and the outer pipe are compressed to form a composite and in a subsequent step, the mineral-insulated socket is produced by removing at least one complete section of the compressed composite.

A high performance differential cable comprises a bulk differential cable formed with a dielectric core having a central cavity and a plurality of wire guides on the outer perimeter. A pair of differential signal conductors (DSC) may be divided into two sets of wires. The smaller wires provide higher signal transmission speeds with lower losses. A paddle board at each end of the bulk differential cable comprises an interconnecting structure for combining signals from the two sets of wires into the two DSCs.
