Patent
Differential signal transmission cable
TL;DR: A differential signal transmission cable has a pair of conductors arranged to be distant from each other and parallel to each other, an insulator covering the pair ofconductors, and a shield conductor wound around the insulator as mentioned in this paper.
Patent
Connection structure and a connection method for connecting a differential signal transmission cable to a circuit board
TL;DR: In this article, a connection structure for connecting a differential signal transmission cable to a circuit board is presented, where exposed parts of the signal line conductors are solder-connected to the signal pads, respectively, and the outer conductor is solder connected to the ground pad via the solder-connecting pin of the shield connecting terminal.
Patent
Differential signaling cable, transmission cable assembly using same, and production method for differential signaling cable
TL;DR: In this article, a differential signaling cable is proposed, in which a pair of signal conductors are provided in parallel, and an insulator is provided on the outer periphery of the insulator.
Patent
Differential signal transmission cable and multi-core differential signal transmission cable
TL;DR: In this paper, a differential signal transmission cable with a conductive layer made of a conductor is considered, where a current is induced when signals propagate through the first and second signal lines.
Proceedings ArticleDOI
High-speed transmission copper cable for 25Gbit/s/lane
TL;DR: In this article, the authors analyzed the generation factor of the intra-pair skew about some cables and converted the S-parameters of cables into the impulse responses and the step responses of each mode.
