CABLE, CABLE ASSEMBLY, AND COMMUNICATION SYSTEM

This application discloses a cable, a cable assembly, and a communications system. The cable includes a power wire, a signal wire, a ground wire, a wrapping layer, a coaxial wire, and a protective layer. The signal wire is used to transmit a low-speed signal. The coaxial wire is used to transmit a high-speed signal. The power wire, the signal wire, and the ground wire are wrapped in the wrapping layer. The coaxial wire is on an outer side of the wrapping layer. The wrapping layer and the coaxial wire are wrapped in the protective layer. In this application, the coaxial wire is separated from the power wire by using the wrapping layer. Therefore, when a signal is transmitted through the cable, transmission performance of the coaxial wire is unlikely to be affected by the power wire. In this way, the cable can still supply electric power and transmit a high-speed signal, and performance of electromagnetic radiation resistance of the cable can be greatly improved.
