Abstract

A differential signaling cable includes a pair of signal conductors provided in parallel, longitudinally within the differential signaling cable, an insulator covering a periphery of the pair of signal conductors as a whole, wherein only the insulator is between the pair of signal conductors, and a shield conductor provided on an outer periphery of the insulator. An interval between the pair of signal conductors is set so that an even-mode impedance of the pair of signal conductors having the interval fixed by embedment within the insulator and covered by the shield conductor, is in a range from 1.5 to 1.9 times an odd-mode impedance for improved skew and differential mode insertion loss experienced during a transmission of high-speed signals of at least 10 Gbps.
