Communication cables incorporating separators with longitudinally spaced projections
A cable may include a plurality of twisted pairs of individually insulated conductors, a separator positioned between the twisted pairs, and a jacket formed around the twisted pairs and the separator. The separator may include a longitudinally extending spine positioned between the plurality of twisted pairs, and one or more respective projections extending from the spine at each of a plurality of longitudinally spaced locations. Each projection at a given spaced location may extend between a respective set of adjacent twisted pairs. Additionally, a respective longitudinal gap of at least approximately five centimeters may be present between each adjacent pair of longitudinally spaced locations.

3. The cable of claim 1 , wherein the one or more respective projections extending at each of the longitudinally spaced locations comprises four projections radially extending from the spine at four respective quadrantal angles.
4. The cable of claim 1 , wherein the one or more projections extending at a first longitudinally spaced location extend from the spine in a set of one or more first directions, and wherein the one or more projections extending at a second longitudinally spaced location adjacent to the first longitudinally spaced location extend from the spine in a set of one or more second directions different than the one or more first directions.
5. The cable of claim 1 , wherein at least one of the projections comprises a first end adjacent to the spine and a second end distal to the first end, and wherein the first end has a first thickness greater than a second thickness of the second end.
6. The cable of claim 5 , wherein a ratio of the first thickness to the second thickness is at least approximately twenty to one.
7. The cable of claim 1 , wherein each of the projections comprises one of an approximately rectangular, trapezoidal, or triangular cross-sectional shape.
8. The cable of claim 1 , further comprising shielding material incorporated into at least one of the projections.
9. A cable comprising:
a plurality of twisted pairs of 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 plurality of longitudinally spaced projections extending from the spine, wherein a respective longitudinal gap between each adjacent pair of longitudinally spaced projections is at least approximately five centimeters; and
a jacket formed around the twisted pairs and the separator.
10. The cable of claim 9 , wherein each of the projections comprises a length in the longitudinal direction that is less than or equal to approximately ninety centimeters.
11. The cable of claim 9 , wherein the plurality of longitudinally spaced projections comprises a plurality of projections at each of a plurality of respective longitudinally spaced locations, and wherein each of the plurality of projections at a longitudinally spaced location extends between a respective adjacent set of twisted pairs.

15. The cable of claim 1 , further comprising shielding material incorporated into at least one of the projections.
16. A cable comprising:
four twisted pairs of individually insulated electrical conductors that extend along a longitudinal direction;
a cross-filler positioned between the four twisted pairs along a longitudinally length of the cable, the cross-filler comprising a central portion and a respective set of four prongs extending from the central portion at a plurality of longitudinally spaced locations, each of the four prongs extending between a respective set of adjacent twisted pairs, wherein a respective longitudinal gap between each adjacent pair of longitudinally spaced locations is at least approximately five centimeters; and
a jacket formed around the twisted pairs and the cross-filler.
