The present invention relates to the technical field of optical communications. Disclosed are a method and apparatus for processing an optical signal. In the solution, a multi-carrier generation apparatus generates a multi-carrier signal based on a single optical source, an offset amount of a frequency of a first path of sub-carrier signal is equal to an offset amount of a frequency of a second path of sub-carrier signal, and a frequency interval between the first path of sub-carrier signal and the second path of sub-carrier signal is known; therefore, an actual frequency interval between the first path of sub-carrier signal and the second path of sub-carrier signal is calculated; or an offset amount between the actual frequency interval and a predetermined frequency interval of the first path of sub-carrier signal and the second path of sub-carrier signal is calculated. Therefore, the problems of low accuracy and influencing the performance of an optical communication system existing in a processing process of an optical signal currently are solved. |
