Abstract
This application provides example optical switching methods and example apparatuses. One example method includes generating K images that are consecutive in time sequence, where a first wavelength channel and at least one second wavelength channel are switched to a blocking state through a same image in the K images, and a value of K depends on a quantity of times that attenuation adjustment is performed for switching the first wavelength channel from a normal state to the blocking state. Information about the K images can then be sent to an optical switching element to enable the optical switching element to perform attenuation adjustment on the first wavelength channel and the at least one second wavelength channel.
