Disclosed are a signal conversion method, and a signal conversion apparatus and system, which are used for reducing, while realizing access of a 1PPS synchronization signal of an RRU, the difficulty of waterproof design of the RRU, the area of a PCB and the volume of the RRU, and reducing the costs of the RRU. The method in the embodiments of the present invention comprises: directly using a signal conversion apparatus to convert the acquired frame format of a 1PPS synchronization signal to obtain a second synchronization signal, wherein the frame format of the second synchronization signal is a frame format supported by a CPRI; and transmitting the converted second synchronization signal to an RRU via an idle CPRI connector on the RRU. |
