The embodiment of the invention provides a data transmission method and device based on a satellite-borne optical fiber interface. The method comprises the following steps: receiving a data packet sent by a data sending end through a satellite-borne optical fiber interface; checking each frame of data in the process of reading and writing the data in the data packet frame by frame; when an error information frame is verified, generating a retransmission signal containing the error information frame; and sending the retransmission signal to the data sending end, so that the data sending end retransmits corresponding data according to the error information frame. According to the embodiment of the invention, the error codes in the high-speed interface transmission process can be effectivelysolved, the link reliability is ensured under the condition of extremely low transmission rate loss, the hardware implementation of the method only uses one dual-port RAM and a small number of Slices,the resource occupancy ra
