The USB universal serial bus is widely used in host computer control and data information transmission due to its plug-and-play, hot-swap support, and flexible use. However, due to cable loss and USB protocol restrictions, high-speed USB signals can only support a transmission distance of 5 meters. In this paper, there shows an engineering application design of the signal transmission scheme based on the USB signal processing chip CH317. Convert hi-speed USB signal into optical Ethernet signal to achieve long-distance transmission of high-speed USB signals. Since there is no test standard at the application layer for hi-speed USB signal, in this paper design a complete test scheme for this transmission method at the hardware layer and application layer according to the existing test standards of hi-speed USB signal and Ethernet. It has certain reference significance for the application of hi-speed USB signal long-distance transmission in engineering.
