Abstract: A data processing method, a communications device, and a communications system, where in a process of transmitting a packet service, a code block stream carrying the packet service is first obtained, then, rate adaptation is performed on the obtained code block stream, and finally, the rate-adapted code block stream is mapped to an optical channel payload unit (OPU) signal. Compared with a mapping manner in which a Generic Framing Procedure (GFP) is used, the data processing method, the communications device, and the communications system feature low processing complexity and/or high bandwidth utilization.

Abstract: Embodiments of the present invention provide a method and an apparatus for transmitting and receiving a client signal in an optical transport network. In the transmission method, a received client signal is mapped into a variable-rate container OTU-N, wherein a rate of the OTU-N is N times as high as a preset reference rate; and then, the variable-rate container OTU-N is split into N optical sub-channel transport units OTUsubs by column, where a rate of each OTUsub equals to the reference rate; next, the N optical sub-channel transport units OTUsubs are modulated onto one or more optical carriers; at last, the one or more optical carriers is transmitted through a fiber.

Abstract: This application provides a data transmission method and apparatus. The method includes: processing, by a network device, a to-be-sent optical data unit ODU to obtain another ODU, where a bit rate of the another ODU is lower than a bit rate of the ODU; and sending, by the network device, the another ODU. In embodiments of this application, the ODU is processed to obtain the another ODU with a lower bit rate, and this helps reduce a rate increase when service data is transmitted in an OTN, so as to reduce an OTN interface rate and OTN costs.
