A shielded combined optical communication and conductor cable is provided. The cable includes a cable body having an inner surface defining a channel within the cable body. The cable includes an optical transmission element located within the channel and an electrical conducting element located within the channel. The cable includes an electromagnetic shield located within the channel and surrounding at least the electrical conducting element. The electromagnetic shield includes an elongate yarn strand or other strand material that supports a metal material that acts to limit electromagnetic fields from traversing across the electromagnetic shield. The strands may be unbraided and may be helically wrapped or longitudinally positioned within the cable body.

Embodiments describe a jacket for use in a telecommunications cable. The jacket includes a jacket body. The jacket body extends along a longitudinal axis of the telecommunications cable. The longitudinal axis passes through a geometrical center of the telecommunications cable. The jacket body includes a first surface. The first surface surrounds core region of the telecommunications cable. The first surface defines a plurality of grooves extending radially outwardly from the longitudinal axis of the telecommunications cable. The plurality of grooves includes a first groove area section and a second groove area section. The first groove area section and the second groove area section are in continuous contact with each other. In addition, the jacket body includes a second surface. The second surface extends along the longitudinal axis of the telecommunications cable and disposed in a spaced relation to the first surface.

A conductive line shield structure includes a first conductive line and a shielding member. The first conductive line includes a conductive part and an insulative part. The shielding member is a sheet including an insulative base material and a metal foil, and is wrapped so as to enclose the first conductive line therein. One side end part of the shielding member overlaps an outside surface of the insulative base material so that one side end part of the insulative base material is in contact with the outside surface of the insulative base material.
