In one example, an electrical cable can include a transmission line conductor, a ground conductor, and a dielectric material. The dielectric material can have at least a portion with a thickness separating the transmission line conductor and the ground conductor that is variable along a length of the electrical cable. Such a non-uniform cable (e.g., a cable having components or features that vary in size and/or geometry along the length of the cable) can provide high IO density with acceptable conductive losses and cross-talk while maintaining a desired impedance. ## Claims ### Claim 1 An electrical cable, comprising: a transmission line conductor;
