Laser communication data frame processing method and device

The invention provides a laser communication data frame processing method and device, and the method comprises the steps: carrying out the clock recovery of to-be-transmitted data after channel coding in a data transmission link, extracting payload information through frame detection, writing the payload information into a transmission memory, reading the data in the memory through a framer, carrying out the grouping and framing transmission, and when a form inquires that a first FIFO queue is not empty, carrying out the framing of the data. If yes, reading a frame sequence needing to be retransmitted, obtaining a corresponding memory address, and reading corresponding data in a transmission memory for retransmission; and in a data receiving link, frame detection is performed on received data, CMI decoding is performed on detected data frames, analysis and verification are performed on the data frames through a frame deframer, if verification is passed, payload information of the data frames is written into a
