摘要：A method and an apparatus for processing optical signals are provided, wherethe method for processing optical signals includes: performing frequency mixing,photoelectric detection, analog/digital conversion, and dispersion compensation onreceived input optical signals, and then obtaining first-path polarization multiplexingoptical signals and second-path polarization multiplexing optical signals; performing aninitialization 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 theinitialization update is performed, to obtain initialized x-path optical signals and initializedy-path optical signals; synchronizing preset x-path training sequences and y-path trainingsequences by using the initialized x-path optical signals and the initialized y-path opticalsignals; and if a synchronization result indicates that polarization cross occurs, rectifyingthe polarization cross.
