A telecommunications cable includes a plurality of twisted pairs of insulated conductors, a separator, a first jacket, one or more barriers and a second jacket. In addition, the plurality of twisted pairs of insulated conductors extends substantially along a longitudinal axis of the telecommunications cable. Further, the plurality of twisted pairs of insulated conductors includes an electrical conductor and an insulation layer. Furthermore, the separator separates each of the plurality of twisted pairs of insulated conductors. Moreover, the first jacket and the second jacket extend substantially along the longitudinal axis of the telecommunications cable. Also, the one or more barriers are positioned between the first jacket and the second jacket.

A shielded electrical cable includes at least two spaced-apart conductors extending side-by-side along a longitudinal cable direction. An insulation electrically insulates the conductors from each other. A cable shield, together with the conductors, extends along the longitudinal cable direction and annularly surrounds the conductors, as seen in cross section. An electrical device is disposed between the conductors and the cable shield. The electrical device is surrounded by the cable shield and disposed on the conductors such that the electrical device is in electrical contact with each of the conductors.
