Disclosed are a frequency offset estimation method and apparatus in an optical transmission network and a storage medium. The method comprises: acquiring a data symbol to be frequency offset estimated, and eliminating a noise phase, a phase generated by a light source and an information phase in the data symbol to be frequency offset estimated; and performing a correlation operation on a data symbol with a set interval in the data symbol after the elimination processing and using a correlation operation result to determine a frequency offset estimation value. |
