Abstract
A signal processing device includes a first photoelectric conversion module and a second photoelectric conversion module; the first photoelectric conversion module is configured to receive an optical signal to be sent that is sent by a time synchronization device, convert the optical signal to be sent into an electric signal to be sent, and transmit the electric signal to be sent to the second photoelectric conversion module, where the optical signal to be sent is generated by the time synchronization device according to an initial electrical signal, and the initial electrical signal includes a service signal and a time synchronization signal; and the second photoelectric conversion module is configured to convert the electrical signal to be sent into a first optical signal of a preset frequency, and send the first optical signal to a first optical path coupling device, causing the first optical path coupling device to couple the first optical signal to an optical signal transmission line for transmission.
