Abstract
The present disclosure provides a data transmission method including: receiving a first-mode optical signal from a first port corresponding to a first port number; converting, according to a correspondence between the first port number and a first mode group number, the received first-mode optical signal into a second-mode optical signal carried in a first mode group identified by the first mode group number, where the second-mode optical signal carried in the first mode group identified by the first mode group number includes an optical signal in one or more modes; and outputting the second-mode optical signal obtained by means of conversion.
Claims16
A data transmission method, comprising:
- receiving a first optical signal from an input port;
- converting, according to a correspondence between an input port of an optical signal and a mode group, the received first optical signal into a second optical signal in one or more modes in a mode group corresponding to the input port;
- and
- multiplexing the second optical signal to a multimode optical fiber for transmission.
A data transmission method, comprising:
- receiving a second optical signal;
- determining a mode group to which the second optical signal belongs;
- and
- outputting, according to a correspondence between an output port and a mode group, the received second optical signal from a corresponding output port.
