Abstract: An optical wavelength measurement apparatus and method may be used to expand a wavelength range that can be detected by using an optical wavelength measurement technology. The measurement apparatus may respectively superimpose to-be-measured light with optical components that are in an optical frequency comb and that correspond to each of a plurality of comb frequency values, to obtain a multiplexed optical signal corresponding to each optical component, and then determine a measured value of a wavelength of the to-be-measured light based on an electrical signal of a multiplexed optical signal corresponding to a target optical component obtained by an electrical beat frequency. The electrical signal corresponding to the target optical component includes a beat frequency signal.
