High bandwidth push-cables for high speed image or video data transmission between a camera head and a cable reel or camera control unit (CCU) are disclosed.

A shielded electrical ribbon cable includes adjacent first and second longitudinal conductor sets where each conductor set includes two or more insulated conductors. The first conductor set also includes a ground conductor that generally lies in the plane of the insulated conductors of the first conductor set. At least 90% of the periphery of each conductor set is encompassed by a shielding film. First and second non-conductive polymeric films are disposed on opposite sides of the cable and form cover portions substantially surrounding each conductor set, and pinched portions on each side of each conductor set. When the cable is laid flat, the distance between the center of the ground conductor of the first conductor set and the center of the nearest insulated conductor of the second conductor set is 1, the center-to-center spacing of the insulated conductors of the second conductor set is 2, and 1/2 is greater than 0.7.

A shielded electrical cable includes one or more conductor sets extending along a length of the cable and being spaced apart from each other along a width of the cable. Each conductor set has one or more conductors having a size no greater than 24 AWG and each conductor set has an insertion loss of less than about ?20 dB/meter over a frequency range of 0 to 20 GHz. First and second shielding films are disposed on opposite sides of the cable, the first and second films including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second films in combination substantially surround each conductor set, and the pinched portions of the first and second films in combination form pinched portions of the cable on each side of each conductor.

A data line that is designed as a coaxial cable and has a line core that extends in a line longitudinal direction. The line core has at least one conductor surrounded at least by insulation and is surrounded by a multi-layer shielding foil, which has a non-conductive layer and a conductive layer. In an overlap region, a free end edge overlaps a further partial region, wherein additionally a conductive connection of the conductive layer at the end edge to the further partial region is formed such that a transverse current flow perpendicular to the longitudinal direction within the conductive layer is enabled. The conductive connection is formed optionally as a conductive strip and/or by a beveled end edge. In particular, the data line is a data line shielded exclusively via the shielding foil. The data line is used in particular in a motor-vehicle electrical system.

The wireline cable includes a plurality of conductors, which includes a core conductor and a concentric conductor disposed around the core conductor, wherein two of the plurality of conductors form a conductor pair, and wherein each of the plurality of conductors is configured to transmit power, data, or both, between the control system and the downhole tool. The wireline cable further includes one or more insulative layers, wherein at least one insulative layer is disposed between any two conductors.

A differential signal cable assembly includes a connector to be connected to a communication device, a first multi-pair cable that is connected to the connector at one end and includes a plurality of first differential signal cables for transmitting differential signals, a second multi-pair cable that includes a plurality of second differential signal cables having a larger conductor diameter than the first differential signal cables, and a connection that is connected to an other end of the first multi-pair cable and one end of the second multi-pair cable such that each of the first differential signal cables is electrically connected to a corresponding one of the second differential signal cables.

An electric cable, in particular a data cable, has a transmission core which is surrounded by a shield and concentrically surrounded by a sheath that includes an outer layer made of an electrically insulating plastic material and a second layer underneath that is made of a semiconducting material. The semiconducting material primary purpose is to divert interference currents.
