Type-C data line refers to the data line of USB type-C interface. USB type-C is a hardware interface specification of universal serial bus (USB). The highlights of USB type-C interface are thinner design, faster transmission speed (up to 10Gbps) and stronger power transmission (up to 100W). The biggest feature of type-C double-sided pluggable interface is that it supports double-sided insertion of USB interface, which formally solves the worldwide problem of "USB is never allowed to be inserted". At the same time, the USB cable used with it must be thinner and lighter.
