Abstract
An interconnection system includes spacers arranged adjacent each other in a row, the spacers having cable sections disposed therein. Each cable section has at least one center conductor and an outer conductive shield. All of the cable sections have one end exposed on a first plane and a second end exposed on a second plane. Electrically conductive contacts are disposed within apertures in a pair of interposers so as to have one end making electrical contact with one of the cable sections and another end extending through its respective aperture in its respective interposer.
