DATA PROCESSING METHOD AND RELATED DEVICE

原文（中国語）

This application provides a data processing method, applied to the optical communication field. The data processing method includes the following steps: A sending device obtains a first 66-bit code block stream of a MAC frame. The sending device obtains a first check field based on the first 66-bit code block stream, the first check field is used to check the first 66-bit code block stream. The sending device adds the first check field to a 66-bit code block following the first 66-bit code block stream. The sending device maps the first 66-bit code block stream and the following 66-bit code block to the payload area of the data frame. The sending device sends the data frame.
