Abstract
A dual axial cable includes first and second signal conductors and a shield. The first and second signal conductors transmit a differential signal. The shield includes a foil wrap spirally wrapped around the first and second conductors to form a plurality of foil wrap sections. Each of the foil wrap sections overlaps an adjacent foil wrap section. The periodicity of a pitch of each of the overlaps varies along a length of the dual axial cable.

A dual axial cable comprising:
- first and second signal conductors to transmit a differential signal;
- and
- a shield including a foil wrap spirally wrapped around the first and second conductors to form a plurality of foil wrap sections, each of the foil wrap sections overlapping an adjacent foil wrap section, a periodicity of a pitch of each of the overlaps varying along a length of the dual axial cable.
A method comprising:
- feeding first and second signal conductors of a dual axial cable through a foil wrapping machine, the first and second conductors to transmit a differential signal;
- and
- spirally wrapping, by the foil wrapping machine, a foil around the first and second conductors to form a shield for the dual axial cable, wherein the spirally wrapping forms a plurality of foil wrap sections, each of the foil wrap sections overlapping an adjacent foil wrap section, a periodicity of a pitch of each of the overlaps varying along a length of the dual axial cable.
A dual axial cable comprising:
- first and second signal conductors to transmit a differential signal;
- and
- a shield including a foil spirally wrapped around the first and second conductors to form a plurality of foil wrap sections, each of the foil wrap sections overlapping an adjacent foil wrap section, a periodicity of a pitch of each of the overlaps varying along a length of the dual axial cable, wherein each of the pitches among the overlaps produces a respective resonance frequency, wherein the periodicity of pitches among the overlaps is varied based a feed rate of the first and second conductors during a wrapping of the dual axial cable.
