A composite cable includes a twisted assembly including a pair of first single core wires and first and second multicore wires that are each arranged in one or the other of regions facing each other across a center plane passing through the central axes of the pair of first single core wires, include an electric wire with a solid (non-hollowed) structure including a first or second twisted pair wire formed by twisting a pair of second or third single core wires with a smaller cross-sectional area than the first single core wire and a first or second inner sheath covering the first or second twisted pair wire so as to fill a space between the pair of second or third single core wires, and have an outer diameter that is not less than 70% and not more than 160% of the outer diameter of the first single core wire.

An electrical connecting assembly includes a first connecting member, a second connecting member, and two pairs of differential conducting wires connected between the first connecting member and the second connecting member and provided to be adjacent to each other. Polarity arrangements of the first cable core and the second cable core of one pair of differential conducting wires at a first end thereof and at a second end thereof are opposite to each other, and polarity arrangements of the first cable core and the second cable core of the other pair of differential conducting wires at a first end thereof and at a second end thereof are identical to each other. The invention may reduce the remote crosstalk of the electrical connecting assembly, and performance of the remote crosstalk characteristics thereof in high frequency is good.

A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

Electrical signal transmission cable systems and methods of using the same are disclosed. The systems and methods use an electrical signal transmission cable system, wherein the electrical signal transmission cable system includes a parallel set of electrical signal transmission cables in electrical communication between an electrical signal transmitting device and an electrical signal receiving device.

In a method for forming a Category 6A communication cable suitable for Power over Ethernet applications, four pairs of individually insulated conductors may be provided, and each of the conductors may have a diameter of at least approximately 0.0240 inches. A respective twist lay for each of the pairs may be selected to result in the communications cable having a propagation delay skew of less than approximately 45 nanoseconds per one hundred meters and a direct current resistance unbalance between any two of the four pairs of less than approximately one hundred milliohms per one hundred meters. Each of the four pairs may be twisted based at least in part on the selected twist lays, and a jacket may be formed around the four twisted pairs.
