Abstract

本发明实施例提供一种信号传输方法、控制器和信号传输系统，该方法包括：控制器接收第一发射机发送的请求信号，该请求信号用于请求向第二接收机发送光信号；该控制器根据该请求信号，通过控制光交换网络中的光开关，在该光交换网络中建立连接该第一发射机与该第二接收机的第二光路；该控制器根据该请求信号向该第二接收机发送用于指示该第二接收机重置为初始状态的重置信号；该控制器在发送该重置信号之后或者同时，向该第一发射机发送确认信号，该确认信号用于指示该第一发射机通过该第二光路向该第二接收机发送光信号。在本发明实施例中，能够实现及时向第二接收机发送该重置信号，能够有效缩短该接收机对接收新的光信号的响应时间。
