Abstract
A cable includes first and second electrically conducting wires, each of the two wires surrounded by a respective isolating dielectric material for a length of the respective wire. A signal propagation skew between the first and second wires may be detected, and a dielectric constant associated with a wire may be changed to mitigate the detected signal propagation skew. The dielectric constant may be changed by removing or adding dielectric material from or to the wire.
Claims12
A cable comprising:
- a first electrically conducting wire with a first circumference and a first length;
- a first dielectric material surrounding the first circumference for a portion of the first length to isolate the first electrically conducting wire;
- a second electrically conducting wire with a second circumference and a second length;
- and
- a second dielectric material surrounding the second circumference for a portion of the second length to isolate the second electrically conducting wire,
- wherein the first electrically conducting wire and the second electrically conducting wire form a pair of conducting wires,
- wherein a signal propagation skew between the first electrically conducting wire and the second electrically conducting wire is detected, wherein signal travels faster over the first electrically conducting wire than the second electrically conducting wire, and a second dielectric constant of the second electrically conducting wire is changed to mitigate the signal propagation skew, and wherein the second dielectric constant of the second electrically conducting wire is changed by iteratively removing a particular portion along a particular length of the second dielectric material farthest from the first electrically conducting wire until the propagation skew between the first electrically conducting wire and the second electrically conducting wire is reduced to below a desired threshold.
