Two electromagnetic interference (EMI) controlling tape application methodologies for unshielded twisted pair (UTP) cable include Fixed Tape Control (FTC) and Oscillating Tape Control (OTC). In FTC, tape application angle and edge placement are controlled to maintain position of the tape edges over a base of nonconductive filler in the cable. In OTC, the tape application angle is continuously varied, resulting in crossing of the tape edges over all of the pairs of conductors with varying periodicity. In both implementations, the filler allows a cylindrical shape.

The foil strip (16) during winding onto the line (10) is elastically deformed radially to the outside and in this way is subjected to radial loading in the direction of the line (10).

Portions of the metal layer and the polymer layer are deformed to form a plurality of dimples, the dimples forming air gaps between the polymer layer and the cable core or a barrier layer if used. The air gaps lower the overall dielectric constant between the metal layer and the cable core, thereby lowering the alien capacitance of the communications cable.
