During simple signal transmission from a USB to a flat ribbon cable, differential-mode interference occurs between the conductor and the data line. By simply adding two additional ground wires it is possible to convert differential-mode to common-mode interference,
USB-C now offers different connector variants ranging from USB 2.0 in Type-C housing to Type-C for a 10 GBit data rate. The housing variants have also become more diverse. Fr...
