In one embodiment, a cable includes a data transmission path disposed about an axial center of the cable and a power transmission path sheathing the data transmission path. The power transmission path includes a power layer and a ground layer, where the power transmission path is characterized by a distributed impedance having at least one frequency dependent impedance characteristic. In some implementations, ground layer shields the data transmission path from electromagnetic interference. In some implementations, the frequency dependent impedance characteristic of the power transmission path is characterized by a capacitance value that satisfies a capacitance criterion at frequencies above a first frequency level. In some implementations, the frequency dependent impedance characteristic of the power transmission path is characterized by an inductance value that satisfies a first inductance criterion at frequencies above a first frequency level.
