Abstract: A signal processing system includes a modulation system and a transmission system. The modulation system is configured to perform first modulation processing on a first subcarrier signal to obtain a second subcarrier signal. The modulation system is further configured to perform second modulation processing on the second subcarrier signal and a first signal light to obtain a transmission signal light. The transmission signal light includes a single-frequency optical carrier signal and an optical sideband signal, and a frequency band of the single-frequency optical carrier signal and a frequency band of the optical sideband signal do not completely overlap. The transmission system is configured to transmit the transmission signal light.
