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 service mapping processing method for an optical transport network, an apparatus, and a system are provided, where the method includes: generating mapping adaptation indication information according to a mapping granularity of a to-be-carried LO ODU, where the mapping granularity is M×g bytes, M is a quantity of timeslots occupied by the to-be-carried LO ODU in an OPUCn, g is a size of a mapping granularity corresponding to each timeslot of the timeslots occupied by the LO ODU, and g is a positive integer greater than 1; mapping, according to the mapping adaptation indication information, the to-be-carried LO ODU to an ODTUCn.M payload area; encapsulating the mapping adaptation indication information into the ODTUCn.M overhead area; encapsulating the ODTUCn.M into an OTUCn; and sending the OTUCn to a receive end device. The method avoids that OTUCns that use different mapping granularities cannot interwork between a receive end and a transmit end.

Abstract: A service data transmission method, a related device, and a digital processing chip, to reduce a transmission latency of service data. The method in the embodiments includes the following steps: a first device encapsulates a channel frame in a transmission frame, where the channel frame is used to carry service data. Next, the first device sends the transmission frame to a second device. A transmission manner of the channel frame is a non-decapsulation manner between an optical transport network and an access network.
