A de-mapping method and device for an Optical Transport Unit (OTU) frame are provided by the present invention, the method includes: setting a receiving reference clock and a de-mapping path according to the highest priority of an OTU frame mapping mode of a local equipment (S102); receiving an OTU frame of the opposite equipment by using the receiving reference clock and the de-mapping path (S104); determining a de-mapping priority of the OTU frame according to a clock recovery result of the received OTU frame and a customer service alarm instruction (S106); and de-mapping the OTU frame of the opposite equipment by using the receiving reference clock and the de-mapping path corresponding to the confirmed de-mapping priority of the OTU frame (S108). By the present invention, the de-mapping efficiency and accuracy of an OTU frame in an optical transport network are improved. |
