A communications cable has a plurality of twisted pairs of insulated conductors, metal foil tape between the twisted pairs, and a cable jacket are disclosed. The metal foil tape can include a substrate, a metal layer on the substrate, and a triboelectric coating on at least the metal layer of the metal foil tape. The triboelectric coating has a charge affinity closer to a charge affinity of the insulated conductors than a charge affinity of the metal layer to prevent charge build up between the conductors and the metal foil tape.

A telecommunications cable (100) has a jacket (110) and a separator (102). The separator (102) has a plurality of curved arms (104) and a plurality of primary arms (112a, 112b, 112c, 112d). Each end of the plurality of curved arms (104) is kept in contact with an inner surface of the jacket (110) to form a plurality of enclosed sections (114). The plurality of primary arms does not touch the inner surface of the jacket and is placed in an offset position relative to one another such that the plurality of primary arms is not aligned in line with one another creating an offset at a point of intersection. The plurality of primary arms has a plurality of equally distributed corrugations (116) projecting inwards towards the inner surface of the jacket (110).

A complex harness includes first electric wires, each of which includes a first center conductor and a first insulation that covers the first center conductor, a cable including second electric wires, each of which includes a second center conductor and a second insulation that covers the second center conductor, and an inner sheath that covers the second electric wires, and an outer sheath covering the first electric wires and the cable collectively. The first electric wires are extended from an end of the outer sheath. The cable is extended from the end of the outer sheath in a state where the second electric wires are collectively covered by the inner sheath in such a manner that an extension length of the cable from the end of the outer sheath is greater than an extension length of the first electric wires from the end of the outer sheath.

An illustrative system includes a sensor component and a controller conductively coupled by way of a first wire and a second wire in a twisted pair configuration. The controller includes a driver configured to drive the sensor component by way of the first and second wires with a drive current in accordance with a gain parameter and a control loop circuit. The control loop circuit is configured to receive a control signal representative of a target current value for the drive current, adjust the gain parameter based on a difference between the target current value and an actual current value of current that is actually being driven through the sensor component, and abstain from adjusting the gain parameter based on current capacitively coupled onto the first and second wires by an external electric field.

A cable includes first and second electrically conducting wires, each of the two wires surrounded by a respective isolating dielectric material for a length of the respective wire. A signal propagation skew between the first and second wires may be detected, and a dielectric constant associated with a wire may be changed to mitigate the detected signal propagation skew. The dielectric constant may be changed by removing or adding dielectric material from or to the wire.
