Claim 15:
16. A data transmission method in an optical transport network (OTN), the method comprising:
receiving an optical transport unit (OTU) frame or a flexible OTN (FlexO) frame;
demapping the OTU frame or the FlexO frame, to obtain an optical data unit (ODU) frame, wherein a payload block at a specific location in a plurality of consecutive payload blocks in a payload area of the ODU frame transports first-type service data, and a payload block at a location other than the specific location in the plurality of consecutive payload blocks transports second-type service data; and
obtaining the first-type service data and the second-type service data from the plurality of consecutive payload blocks,
wherein
the first-type service data comprises first service data;
the plurality of consecutive payload blocks constitutes one transport period; and
a location of a payload block occupied by the first service data in a first transport period is the same as a location of a payload block occupied by the first service data in a second transport period.
