Abstract
This application discloses an optical signal control method and apparatus, and belongs to the optical communication field. The apparatus includes: a light source, configured to output a first optical signal; an optical switch module, configured to receive the first optical signal and an external second optical signal, and output a third optical signal; and a detection module, configured to detect whether a power change of the second optical signal on at least one wavelength channel is greater than a preset power change threshold, if so, the optical switch module adjusts on/off states of at least one wavelength channel of the received first optical signal and the at least one wavelength channel of the received second optical signal, so that an adjusted first optical signal and an adjusted second optical signal are combined to obtain the third optical signal.
