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

A 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 tape separator disposed between the plurality of twisted pairs of insulated conductors and arranged such that the configurable tape separator separates the first twisted pair of insulated conductors from the second twisted pair of insulated conductors without completely surrounding any one twisted pair of the plurality of twisted pairs of insulated conductors;
• and
• a jacket enclosing the plurality of twisted pairs of insulated conductors and the configurable tape separator;
• wherein the configurable tape separator comprises a dielectric tape, a first at least partially conductive layer disposed on a first side of the dielectric tape, and a second conductive layer disposed on a second side of the dielectric tape.
