Abstract: A cable includes a jacket surrounding first and second insulated conductors and a first dielectric tape, wherein the first insulated conductor is twisted with the second insulated conductor with the first dielectric tape residing therebetween to form a first twisted pair. The cable's jacket may also surround a similarly formed second twisted pair. In alternative or supplemental embodiments of the invention, the first insulated conductor includes a first conductor surrounded by a layer of first dielectric insulating material having a radial thickness of about 7 mils or less; the first dielectric tape has a first width which is equal to or less than the diameters of the first and second insulated conductors plus a thickness of the first dielectric tape; the first dielectric tape has a cross sectional shape, which presents first and second recessed portions for seating the first and second insulated conductors; twist lengths of the first and second twisted pairs are between approximately 0.22 to 0.

Abstract: A network cable including a plurality of conductors and an associated crossweb having one or more fins of substantially elliptical cross-sectional shape. The crossweb runs longitudinally along at least a portion of a length of the conductors, and includes a central region approximately in a center of the cable and a plurality of fins extending outwardly from the central region, with a given one of the fins separating at least a first one of the conductors from at least a second one of the conductors. At least the given one of the fins has a variable thickness along a cross-sectional length thereof from the central region to an opposing end of the fin with a maximum of the variable thickness being in a portion of the fin between the central region and the opposing end of the fin.

Abstract: An electrical cable has twenty or more twisted pairs of conductors therein formed into units of three twisted pairs and four twisted pairs, with a centrally located additional four pair unit. Dielectric film or tape partially surrounds either the three pair units or the four pair units or both to maintain separation of each unit from adjacent units. The conductors of the pairs in each unit have different twist lengths relative to the other conductors in the unit, and the units have different lay lengths, depending on the number of pairs in each unit.
