Abstract:
1. An information transmission cable comprising: first and second signal carrying conductors of specified length, each of said signal carrying conductors disposed to carry information signals and having a longitudinal axis; an insulating structure comprising an amount of specified dielectric insulation material, said insulating structure positioned to surround said first and second signal carrying conductors along their respective lengths, and acting to maintain said first and second signal carrying conductors in spaced apart parallel relationship with each other; a first drain conductor positioned proximate to said first signal carrying conductor in spaced apart parallel relationship, and further positioned in a first prespecified relationship with a reference line that intersects the respective longitudinal axes of said first and second signal carrying conductors and lies in a plane orthogonal thereto; a second drain conductor positioned proximate to said second signal carrying conductor in spaced apart parallel relationship, and further positioned in a second prespecified relationship with said reference line; and shielding material spirally wrapped around said first and second signal carrying conductors, said first and second drain conductors and said insulating structure, collectively; wherein: said first drain conductor is at least partially positioned in a first zone, wherein the intersection of said first zone and said orthogonal plane defines a first area in said orthogonal plane that is bounded at least in part by portions of two first boundary lines, the first boundary line and the other first boundary line, that each intersect said reference line at the axis of said first signal carrying conductor, said first boundary line being oriented to an angle of approximately 30 degrees with respect to said reference line in a clockwise direction, and the other first boundary line being oriented to an angle of approximately 30 degrees with respect to said reference line in a counter clockwise direction; and said second drain conductor is at least partially positioned in a second zone, wherein the intersection of said second zone and said orthogonal plane defines a second area in said orthogonal plane that is bounded at least in part by portions of two second boundary lines, the second boundary line and the other second boundary line, that each intersect said reference line at the axis of said second signal carrying conductor, said second boundary line being oriented to an angle of approximately 30 degrees with respect to said reference line in a clockwise direction, and the other second boundary line being oriented to an angle of approximately 30 degrees with respect to said reference line in a counter clockwise direction.
