Multiple differential pair cable
First Claim
1. A high speed data transmission cable having a plurality of differential conductor pairs, a length and a central axis comprising:
- each differential pair comprising two conductors generally 180°
apart from each other;
a first insulation electrically insulating the conductors from each other;
an electrically conductive shield surrounding the conductors and the insulation; and
a second insulation surrounding all the differential pairs and distancing the differential pairs from the shield;
wherein the second insulation layer serves to separate the distance between any one of the conductors and the shield to be greater than the distance between that conductor and the central axis of the cable so as to lower attenuation of the cable.

Abstract
A quad or dual differential pair cable for bi-directional high speed differential signal transmission has a first differential pair of conductors and a second differential pair of conductors. The conductors extend in substantially parallel relation to one another and are electrically insulated from each other by an insulating dielectric. The dielectric and the conductors are surrounded by a conductive metal shield. The dielectric insulates the conductors both from each other and from the shield and is sufficiently crush resistant to maintain the conductors in substantially parallel relation to one another over the length of the cable, The shield may be covered with an optional jacket. Each wire of a differential pair of wires are oriented 180 degrees apart from one another. The distance between any one of the conductors and the shield is equal to or greater than the distance between that conductor and a center axis of the cable.

8. A quad pair data transmission cable having a length and a central axis comprising:
-
four electrical conductors defining first and second diagonal pairs of differential pair conductors, the conductors being spaced apart in generally constant relative position to each other over the length of the cable; insulating dielectric surrounding each of the four conductors, insulating the conductors from each other; an electrically conductive shield surrounding the conductors and the insulating dielectrics; and a layer of insulation surrounding all the differential pairs and distancing the differential pairs from the shield; wherein the layer of insulation surrounding the differential pairs serves to increase the distance between any one of the conductors and the shield to be greater than the distance between that conductor and the central axis of the cable so as to lower attenuation of the cable. - View Dependent Claims (9, 10, 11, 12)
