Multi-pair data cable with configurable core filling and pair separation

An unshielded twisted pair communications cable comprising:

• a plurality of twisted pairs of insulated conductors including a first twisted pair of insulated conductors and a second twisted pair of insulated conductors;
• a configurable pair separator that, prior to cabling, comprises a substantially flat, non-conductive tape disposed between the plurality of twisted pairs of conductors and that is arranged so as to separate the first twisted pair of insulated conductors from the second twisted pair of insulated conductors;
• and
• a jacket enclosing the plurality of twisted pairs of insulated conductors and the configurable pair separator;
• wherein the plurality of twisted pairs of insulated conductors and the configurable dielectric separator are cabled about a common axis to form the unshielded twisted pair communications cable.

An unshielded twisted pair communications cable comprising:

• a plurality of twisted pairs of insulated conductors including a first twisted pair and a second twisted pair;
• a separator disposed among the plurality of twisted pairs of insulated conductors so as to separate the first twisted pair from the second twisted pair;
• and
• a jacket enclosing the plurality of twisted pairs of insulated conductors and the separator;
• wherein the separator comprises a substantially non-conductive body and is constructed such that, when a portion of the jacket is removed from an end of the cable to expose the plurality of twisted pairs and the separator, the exposed separator is substantially flat.
