A method and an apparatus for processing optical signals are provided, where the method for processing optical signals includes: performing frequency mixing, photoelectric detection, analog/digital conversion, and dispersion compensation on received input optical signals, and then obtaining first-path polarization multiplexing optical signals and second-path polarization multiplexing optical signals; performing an initialization update process on filter coefficients, and performing polarization compensation on the first-path polarization multiplexing optical signals and the second-path polarization multiplexing optical signals by using the filter coefficients on which the initialization update is performed, to obtain initialized x-path optical signals and initialized y-path optical signals; synchronizing preset x-path training sequences and y-path training sequences by using the initialized x-path optical signals and the initialized y-path optical signals; and if a synchronization result indicates that polarization cross occurs, rectifying the polarization cross. |
