Composite flexible circuit planar cable

A composite flexible circuit planar cable, comprising:

• a flat cable, having a first end, a second end, and a plurality of parallel and non-jumping conductor lines extending and laid in the form of a flat cable between the first end and the second end;
• a first section, having a flat cable connection end, an external connection end, and a first plurality of conductive lines extending and laid between the flat cable connection end and the external connection end, the flat cable connection end of the first section being connected to the first end of the flat cable and electrically connected to the conductor lines extending to the first end of the flat cable, each of said first plurality of conductive lines being positioned to define a first arrangement of said first plurality of conductive lines with said parallel and non jumping conductor lines;
• and
• a second section, having a flat cable connection end, an external connection end, and a second plurality of conductive lines extending and laid between the flat cable connection end and the external connection end, the flat cable connection end of the second section being connected to the second end of the flat cable and electrically connected to the conductor lines extending to the second end of the flat cable, each of said second plurality of conductive lines being positioned to define a second arrangement of said second plurality of conductive lines with said parallel and non-jumping conductor lines, said first arrangement being different from said second arrangement, wherein the first section comprises at least one jumping line, the jumping line interchangeably connecting a selected first conductive line of the first section to another selected conductive line of said flat cable;
• wherein the plurality of conductor lines of the flat cable comprise at least a pair of differential signal conductor lines, the first plurality of conductive lines of the first section comprising first differential signal lines corresponding to the differential signal conductor lines, the second plurality of conductive lines of the second section comprising second differential signal lines corresponding to the differential signal conductor lines;
• and
• wherein the plurality of conductor lines of the flat cable comprises at least one grounding line, the first plurality of conductive lines of the first section comprising a first grounding conductive line corresponding to the grounding line, the second plurality of conductive lines of the second section comprising a second grounding conductive line corresponding to the grounding line.
