Abstract: A method for establishing a data model and an apparatus, where a network element may create an optical signal group that includes optical signals with different wavelengths. After selecting a first optical signal group and obtaining first data of the first optical signal group, the network element may reflect, based on a first model established based on the first data of the first optical signal group, a noise coefficient and a gain that are obtained after an optical signal in the optical signal group of different wavelength combinations passes through the network element.
