Abstract: A cable exhibiting reduced crosstalk between transmission media includes a core having a profile with a shape which defines spaces or channels to maintain a spacing between transmission media in a finished cable. The core is formed of a conductive material to further reduce crosstalk. A method of producing a cable introduces a core as described above into the cable assembly and imparts a cable closing twist to the assembly.

Abstract: Cables including a plurality of twisted pairs of insulated conductors and a core disposed between the plurality of twisted pairs of insulated conductors so as to separate at least one of the plurality of twisted pairs of insulated conductors from others of the plurality of twisted pairs of insulated conductors. In one example, a cable may include a jacket having a plurality of protrusions. In another example, the core may include one or more pinch points to facilitate breaking of the core. In yet another example, two or more cables may be bundled, and possibly twisted, together to form a bundled cable.
