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: A first optical network device groups a plurality of FlexO instance frames into one group, where each of the plurality of FlexO instance frames carries one OTU signal; then, performs multiplexing on the plurality of FlexO instance frames grouped into one group, to generate one first FlexO frame; next, performing scrambling and FEC processing on the first FlexO frame to generate one second FlexO frame and send it to a second optical network device. If a rate of the FlexO instance frame is 100 Gbps and two FlexO instance frames are grouped into one group, the 200 G optical module can be used in the transmission method.

Abstract: In a service signal processing method, an optical network unit (ONU) receives a service signal; maps the service signal to a flexible optical service unit frame; and sends a first passive optical network transmission convergence frame to an optical line terminal (OLT), where the flexible optical service unit frame is encapsulated in the first passive optical network transmission convergence frame, and where the flexible optical service unit frame is used to carry the service signal in a passive optical network (PON) and an optical transport network (OTN). In this application, the flexible optical service unit frame can be transmitted in both the PON and the OTN, and the ONU and the OLT do not need to parse the service signal.

Abstract: A data transmission method in an optical transport network includes: mapping first-type service data to a payload block at a specific location in a plurality of consecutive payload blocks, where the plurality of consecutive payload blocks occupy a payload area of an optical data unit (ODU) frame; mapping second-type service data to a payload block at any location in the plurality of consecutive payload blocks other than the at least one specific location; mapping the ODU frame to an optical transport unit (OTU) frame or a flexible OTN (FlexO) frame; and sending the OTU frame or the FlexO frame. In an applicable scenario, service data is transmitted in a hybrid manner.

Abstract: Embodiments of this application provide a signal frame processing method and a related device. A sink node performs delay compensation on a received service, so that delay variation generated in a transmission process of the service can be effectively eliminated. The method in embodiments of this application includes the following steps. First, the sink node receives a signal frame. A payload area of the signal frame is used to bear a target service, and an overhead area of the signal frame includes a node quantity field. Then, the sink node determines, based on the node quantity field, a quantity of nodes through which the target service passes during transmission. Further, the sink node performs delay compensation on the target service based on the quantity of nodes.
