A differential signal transmission cable structure for transmitting differential signals having GHz frequency band in the present invention is provided with a differential signal transmission pair cableconnecting a driver circuitand a receiver circuit, for transmitting differential signals having GHz frequency band, and a power supply ground transmission pair cableconnecting ground and a first power supplyconnected to the driver circuit and ground and a second power supplyconnected to the receiver circuit. Further characteristic impedance of the differential signal transmission pair cable is matched to that of the driver circuit and the receiver circuit, thereby enabling TEM waves of differential signals having GHz frequency band transmission mode to be maintained when the differential signals are transmitted.

Transmission cable structure for GHz frequency band signals and connector used for transmission of GHz frequency band signals

A cable wherein even when there is a substantial volume of cable identifying information for identifying the cable, all of that cable identifying information can be simply and speedily written-in. This cable has a cable core, an integrated member with a chain of RFIDs including a plurality of RFID elements arranged at suitable intervals along a longitudinal direction of the cable core, to and from which cable identifying information can be written-in and read-out by transmission of electromagnetic energy, and a transmission coaxial cable for collectively writing-in cable identifying information to all of the RFID elements.
