| 摘要 |
Disclosed are a signal transmission method, apparatus and system. The method comprises: each input port of a first mode multiplexer receives a first optical signal; the first mode multiplexer generates a second optical signal according to a correspondence between the input ports and modules, the second optical signal being an optical signal in any mode, of a module corresponding to the input port, and one input port being corresponding to one module; and the first mode multiplexer outputs the second optical signal. In embodiments of the present invention, big data is transmitted by increasing the transmission capacity of a single optical fiber, and the transmission capacity is rapidly increased, thereby improving the total bandwidth utilization rate of a system. |
