1. A method for transmitting a signal in an Optical Transport Network (OTN), comprising:
mapping the signal to a low-rate Optical channel Payload Unit (OPU) of a low-rate Optical channel Data Unit (ODU), wherein the low-rate ODU comprises an ODU overhead section and the low-rate OPU, the low-rate OPU comprises an OPU overhead section and an OPU payload section, the low-rate ODU has a bit rate of 1, 244, 160 Kbps±20 ppm, and the OPU payload section has a bit rate of 1, 238, 954.31 Kbps±20 ppm;
generating OPU overhead bytes and filling the OPU overhead bytes into the OPU overhead section of the low-rate OPU;
generating ODU overhead bytes and filling the ODU overhead bytes into the ODU overhead section of the low-rate ODU;
multiplexing the low-rate ODU to an Optical channel Data Unit-k (ODUk), wherein the ODUk has a bit rate higher than the bit rate of the low-rate ODU; and
transmitting the ODUk via the OTN.
