1. A service data processing method, comprising:
receiving, by a transmit end, service data;
mapping, by the transmit end, the service data to a plurality of optical transport network (OTN) data frames, wherein
the OTN data frame comprises:
an overhead area, the overhead area is used to carry overheads of the service data, and a length of the overhead area is a fixed value and remains constant as a transmission rate of the OTN data frame changes; and
a payload area, the payload area is used to carry the service data, and a length of the payload area is positively correlated with the transmission rate of the OTN data frame and increases as the transmission rate of the OTN data frame increases; and
sending, by the transmit end, the plurality of OTN data frames.
