A cable (100) includes a plurality of wires (10) and a jacket (20) enclosing the wires. The wires includes a plurality of differential signal wires (11) for transmitting high speed signal, a detection signal wire (12), at least one auxiliary signal wire (13), and a plurality of lower speed signal wires (14). All of the differential signal wires, the detection signal wire and the at least one auxiliary signal wire are arranged at an outer peripheral of and enclosing the lower signal wires. Each two adjacent differential signal wire pairs are separated by one of the detection signal wire and the at least one auxiliary signal wire.

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 shielded electrical cable includes a conductor set and two generally parallel shielding films disposed around the conductor set. The conductor set includes one or more substantially parallel longitudinal insulated conductors. The shielding films include a parallel portion wherein the shielding films are substantially parallel. The parallel portion is configured to electrically isolate the conductor set.

A shielded cable includes adjacent first and second conductor sets, each conductor set includes a pair of insulated conductors. At least 90% of a periphery of each conductor set is encompassed by a shielding film. The cable also includes first and second non-conductive polymeric films disposed on opposite sides of the cable. The polymeric films include cover portions and pinched portions. In transverse cross section, the cover portions of the polymeric films in combination surround the conductor sets, and the pinched portions of the polymeric films in combination form pinched portions of the cable on each side of the cable. When the cable is laid flat, a center-to-center spacing of the pair of insulated conductors for the first conductor set is ?1 and a center-to-center spacing of the first and second conductor sets is ?. ?/?1 is less than 4.

The parallel portion is configured to electrically isolate the conductor set.

A dual axial cable includes first and second signal conductors, a shield, and a drain wire. The first and second signal conductors transmit a differential signal. The shield is spirally wrapped around the first and second conductors, and causes a resonant characteristic of the dual axial cable. The drain wire provides a return path for the differential signal in the dual axial cable. The drain wire is roughened to a specific amount of roughness, which reduces signal loss at resonant frequencies of the resonant characteristic caused by the shield.

A shielded electrical ribbon cable includes a plurality of conductor sets. Each conductor set is surrounded by a shield and includes two insulated conductors. First and second non-conductive polymeric layers are disposed on opposite sides of the cable. The polymeric layers include cover portions and pinched portions. The cover portions surround the plurality of conductor sets, and the pinched portions form pinched portions on each side of the cable. The cable includes a transition portion on each side of the cable. At least one of the polymeric layers has a radius of curvature of at least 50 microns across an entire width of the cable. For at least one of the polymeric layers, the ratio of the minimum radius of curvature in the cover portions to the minimum radius of curvature in the transition portions is from 2 to 15.
