The present disclosure describes methods of manufacture and implementations of hybrid separators for data cables having conductive and non-conductive or metallic and non-metallic portions, and data cables including such hybrid separators. A hybrid separator comprising one or more conductive portions and one or more non-conductive portions may be positioned within a data cable between adjacent pairs of twisted insulated and shielded or unshielded conductors so as to provide physical and electrical separation of the conductors. The position and extent (laterally and longitudinally) of each conductive portion and each non-conductive portion may be selected for optimum performance of the data cable, including attenuation or rejection of cross talk, reduction of return loss, increase of stability, and control of impedance.

A shielded cable includes a first insulated wire including a first central conductor, and a first insulating layer provided around the first central conductor, a second insulated wire including a second central conductor, and a second insulating layer provided around the second central conductor, the second insulated wire being disposed parallel to the first insulated wire, a third insulating layer provided around the first insulated wire and the second insulated wire, a shielding layer provided around the third insulating layer, a drain wire in contact with the shielding layer, and a fourth insulating layer provided around the shielding layer and the drain wire.

The present disclosure relates to a composite cable, which comprises a first wire assembly and a second wire assembly, and each wire of the second wire assembly is surrounded by an insulating layer. The composite cable further comprises: a sheath made of insulating material and configured to enclose the first wire assembly and the second wire assembly; and a shield comprising different kinds of metal wires and configured to surround the first wire assembly, wherein the first wire assembly is capable of transmitting signals, and the second wire assembly is capable of transmitting power supply. The composite cable according to the present disclosure is excellent in shielding performance for different requirements.

A communication cable that has a reduced diameter while ensuring a required magnitude of characteristic impedance. The shielded communication cable contains a twisted pair containing a pair of insulated wires twisted with each other. Each of the insulated wire contains a conductor that has a tensile strength of 400 MPa or higher, and an insulation coating that covers the conductor. The shielded communication cable 1 further contains a shield that is made of a conductive material and surrounds the twisted pair. The shielded communication cable has a characteristic impedance of 10010.

A method and apparatus for testing shield continuity are provided. In the method and apparatus, a transmitter transmits a first signal in common mode over a plurality of conductors of a cable or cabling installation having a shield. The first signal is transmitted in the common mode at a first end of the plurality of conductors. A receiver receives a plurality of second signals representative of the first signal at a second end of the plurality of conductors, respectively, and outputs data representative of the plurality of second signals. A processor receives the data representative of the plurality of second signals, determines a common mode insertion loss for the cable or cabling installation based on the plurality of second signals, determines, based on the common mode insertion loss, whether the shield is continuous or discontinuous and outputs data representative of whether the shield is continuous or discontinuous.

A data cable for high-speed data transmission at signal frequencies of >10 GHz includes at least one core pair which is surrounded by a film-shaped pair shield having an inner shielding film and an outer shielding film which, are in electrical contact with one another and in which the inner shielding film is wound around the core pair. By virtue of this measure, an undesired resonance effect is avoided which, in previously wound pair shields, has not allowed use for relatively high signal frequencies. At the same time, an undesired common-mode signal, which would occur in the case of a longitudinally folded shielding film, is thus suppressed.

A cable may include a plurality of twisted pairs of individually insulated conductors, a separator positioned between the twisted pairs, and a jacket formed around the twisted pairs and the separator. The separator may include a longitudinally extending spine positioned between the plurality of twisted pairs, and a plurality of projections extending from the spine with each projection extending between a set of adjacent twisted pairs. Additionally, a plurality of longitudinally spaced radial ridges may be incorporated into the separator. Each ridge may extend from a surface of one of the plurality of projections towards one of the plurality of twisted pairs in order to provide increased separation distance.

A cable includes a plurality of wires, an wrapping tape covering the outside of the wires, a shielding layer coated on the outside of the wrapping tape and an insulating cover coated on the outside of the shielding layer, the shielding layer includes a plurality of conductors, wherein the shielding layer includes fibers mixed with the conductors.
