1. A cable comprising:

  • a plurality of twisted pairs, each of the plurality of twisted pairs comprising two individually insulated electrical conductors that extend along a longitudinal direction;

    a separator comprising;

    a longitudinally extending spine positioned between the plurality of twisted pairs; and

    a first set of projections respectively extending away from the spine in a first direction at a first plurality of spaced locations along a longitudinal length of the spine, each projection included in the first set of projections being non-continuous along the longitudinal length of the spine and having a distance of projection from the spine that is at least approximately half the diameter of one of the plurality of twisted pairs; and

    a second set of projections respectively extending away from the spine in a second direction different than the first direction at a second plurality of spaced locations along the longitudinal length of the spine different than the first plurality of spaced locations, each projection included in the second set of projections being non-continuous along the longitudinal length of the spine and having a distance of projection from the spine that is at least approximately half the diameter of one of the plurality of twisted pairs;

    a third set of projections respectively extending away from the spine in a third direction different than the first and second directions at a third plurality of spaced locations along the longitudinal length of the spine different than the first and second pluralities of spaced locations, each projection included in the third set of projections being non-continuous along the longitudinal length of the spine and having a distance of projection from the spine that is at least approximately half the diameter of one of the plurality of twisted pairs; and

    a fourth set of projections respectively extending away from the spine in a fourth direction different than the first, second, and third directions at a fourth plurality of spaced locations along the longitudinal length of the spine different than the first, second, and third pluralities of spaced locations, each projection included in the fourth set of projections being non-continuous along the longitudinal length of the spine and having a distance of projection from the spine that is at least approximately half the diameter of one of the plurality of twisted pairs,wherein no more than a single projection included in any of the first, second, third, and fourth sets of projections extends from the spine at any given cross-sectional location along the longitudinal length of the spine, andwherein the projections included in the first, second, third, and fourth sets of projections extend from the spine and alternate between the first, second, third, and fourth sets of projections in approximately ninety degree increments along the longitudinal length of the spine;

    a jacket formed around the plurality of twisted pairs and the separator.
