摘要： Embodiments of this application relate to the field of optical communications, and in particular, to a technology of processing data in an optical transport network. In a method for processing data, an optical network device extracts Ethernet data from a data frame of one path, converts the Ethernet data into another format, and places the Ethernet data converted into the another format into a data frame of another path. The optical network device is a destination device of the path and a source device of the another path. In addition, the optical network device further extracts overhead information from the data frame of the path, and inserts the overhead information into the data frame of the another path. The method for processing data provided in this application can implement interworking between different types of Ethernet interfaces. In addition, by using cross-path overhead processing, the method reduces path management complexity.

摘要： A first optical network device groups a plurality of FlexO instance frames into one group, where each of the plurality of FlexO instance frames carries one OTU signal; then, performs multiplexing on the plurality of FlexO instance frames grouped into one group, to generate one first FlexO frame; next, performing scrambling and FEC processing on the first FlexO frame to generate one second FlexO frame and send it to a second optical network device. If a rate of the FlexO instance frame is 100 Gbps and two FlexO instance frames are grouped into one group, the 200 G optical module can be used in the transmission method.
