Abstract
Embodiments of this application provide a wavelength configuration apparatus and system, and a wavelength configuration method. The wavelength configuration system includes an electrical signal processing apparatus and a multiplexer/demultiplexer apparatus. The multiplexer/demultiplexer apparatus sends an optical signal to indicate a specified wavelength to be configured by the electrical signal processing apparatus. The electrical signal processing apparatus automatically configures a wavelength of an optical transceiver interface after receiving the optical signal.
