DIFFERENTIAL SIGNALING CABLE, TRANSMISSION CABLE ASSEMBLY USING SAME, AND PRODUCTION METHOD FOR DIFFERENTIAL SIGNALING CABLE |
| 摘要 |
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. |

1. A differential signaling cable, comprising:
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, wherein 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, the improved skew and differential mode insertion loss being in comparison both to skew experienced with below 1.5 times the odd-mode impedance and differential mode insertion loss experienced with above 1.9 times the odd-mode impedance, and wherein the pair of signal conductors is configured such that the even-mode impedance is in a range from 75Ω to 95Ω. |
