摘要： The embodiments of the present disclosure provide a method, an apparatus, and a system for transmitting service data on an optical transport network. The method includes: mapping the service data into a low order flexible optical channel data unit (ODUflex); multiplexing multiple low order ODUflexs into a high order ODUflex; adding a forward error correction (FEC) overhead into the high order ODUflex to generate a flexible optical channel transport unit (OTUflex); and splitting the OTUflex into multiple data channel signals, and modulating the data channel signals to orthogonal frequency division multiplexing subcarriers to send the orthogonal frequency division multiplexing subcarriers. The foregoing solution provides OTUflexs. Therefore, the network adapts service data for flexibly variable line rates of the optical transport network through a control protocol, and transmits service data of different rates to meet the development requirements of higher-rate optical transport networks.

摘要： A method for transporting a client signal in an optical transport network (OTN) includes steps as follows. A byte number Cn of a client signal transported in a OTN frame period is generated according to a client signal clock and a system clock. If the Cn of the OTN frame falls in a certain range, a predetermined area in an optical channel payload unit-k (OPUk) overhead field is identified as normal, and the Cn is filled in the OPUk overhead field of the OTN frame. Therefore, the reliability for transporting the client byte number can be improved and an OPUk overhead byte space needed for transporting the client signal byte number can be saved.
