Methods for forming continuous shields for use in a cable are provided. A first layer of longitudinally extending dielectric material may be provided, and a second layer of longitudinally extending electrically conductive material may be formed on the first layer. At a plurality of spaced locations along a longitudinal direction, respective gaps may be formed through both the first layer and the second layer, and each gap may span partially across a width of the second layer. Additionally, at each of the plurality of spaced locations, the gaps may result in the formation of one or more fusible elements of the electrically conductive material spanning between an adjacent set of longitudinally spaced segments of the electrically conductive material. Each fusible element may provide electrical continuity between the adjacent set of longitudinally spaced segment and may further have a minimum fusing current between 0.001 amperes and 0.500 amperes.

Cables incorporating a separator positioned between two or more subcomponents are described. A separator may extend in a longitudinal direction and include a body portion having an asymmetrical cross-sectional. Additionally, an outer periphery of the body portion may define a plurality of longitudinally extending channels including a first channel having a first cross-sectional area and a second channel having a second cross-sectional area different than the first cross-sectional area. At least one cavity may optionally extend through the body portion along the longitudinal direction. A first cable subcomponent including first transmission media may be positioned within the first channel, and a second cable subcomponent including second transmission media may be positioned within the second channel. A jacket may be formed around the separator and the subcomponents.
