A signal transmission method includes receiving, by a controller, a request signal sent by a first transmitter. The method includes establishing, by the controller according to the request signal, a second optical path that connects the first transmitter to the second receiver in the optical switching network (OSN). The method includes sending, by the controller, to the second receiver according to the request signal, a reset signal used to instruct the second receiver to be reset to an initial state. The method includes sending, by the controller, an acknowledgement signal to the first transmitter. The acknowledgment signal is used to instruct the first transmitter to send, by using the second optical path, an optical signal to the second receiver.
