Patent ID: 7211734

Claim:
A conversion apparatus for connecting from a high speed data cable having two orthogonal pairs of conductors comprising: two or more stacked dielectric boards supporting electrical traces, wherein said traces are transmission lines; a ground plane between said stacked boards; plated through holes in said boards respectively in contact with said traces; first conductors connected to plated through holes on one of said boards; second conductors connected to plated through holes on another of said boards; electrical connections between said first conductors and one of said two orthogonal pairs; electrical connections between said second conductors and the other of said two orthogonal pairs; a first high speed data cable having a single pair of conductors; a second high speed data cable having a single pair of conductors; electrical connections between said traces on one of said dielectric boards and the conductor pair of said first high speed data cable; and electrical connections between said traces on another of said dielectric boards and the conductor pair of said second high speed data cable.
