Abstract: Embodiments of the present invention relate to a signal transmission method, transmitter, and signal transmission system. The method includes: obtaining, by a sending end, information about a power fading point of a fiber channel between the sending end and a receiving end; determining, by the sending end and according to the information about the power fading point, a subcarrier that is used to send a service signal to the receiving end on the fiber channel, where a frequency of the determined subcarrier is different from that of the power fading point; and sending, by the sending end, a service signal to the receiving end by using the determined subcarrier. According to the embodiments of the present invention, validity of a signal spectrum is ensured, and therefore it is ensured that transmitted data can be effectively recovered at a receiving end.
