Abstract: A method for determining an optical signal power change, wherein the method includes: A first optical signal that includes a plurality of wavelength signals is obtained, where the plurality of wavelength signals are distributed in a plurality of bands. Then, an optical power of each band and a center wavelength signal of each band are detected, and a preset single-wavelength transmit power and a preset coefficient are obtained. Next, an equivalent quantity N of equivalent wavelength signals is determined, and an equivalent wavelength signal corresponding to the first optical signal is determined. Further, a target power that is used to compensate for a first power change value of the first optical signal in transmission over an optical fiber is determined based on the preset coefficient, the equivalent wavelength signal, the equivalent quantity, and the preset single-wavelength transmit power.

Abstract: This application provides a spectrum resource configuration method, a network device, and a system. The method includes: A network device determines spectrum resources to be used by a to-be-opened channel, where the spectrum resources to be used by the to-be-opened channel include first spectrum resources and a second spectrum resource, the first spectrum resources are original spectrum resources of the to-be-opened channel, the second spectrum resource is some of original spectrum resources of an adjacent channel of the to-be-opened channel, and the original spectrum resources of the adjacent channel are adjacent to the original spectrum resources of the to-be-opened channel; and opens the to-be-opened channel based on the spectrum resources to be used by the to-be-opened channel.
