ABSTRACT:
A method for signal transporting in an optical transport network comprises: presetting frame structures for an optical channel payload unit OPUx and an optical channel data unit ODUx of a 5G-path transporting constant-bit-rate CBR5G rate-level signals in an optical channel layer; and according to the frame structures of the optical channel payload unit OPUx and the optical channel data unit ODUx, mapping and multiplexing the constant-bit-rate CBR5G rate-level signals to the optical channel layer of the optical transport network for transport through the optical transport network. The present invention also discloses a corresponding device for signal transporting. Since there are provided OPUx/ODUx/OTUx for transporting CBR5G rate-level signals in the OTN, thus enabling transparent transport of the CBRG5 signals in the OTN as well as direct scheduling, supervision and management on the CBR5G signals in the OTN.
