Abstract: Disclosed are a data communications device of a common data link communications system and an operation method thereof. According to embodiments of the present invention, the data communications device of the common data link communications system comprises a packet generation unit for generating packets by adding packet information to signal data and images received from one or more sensors; a packet multiplexing unit for time-multiplexing the packets and outputting the multiplexed packets; a variable frame generation unit for generating a variable frame by sequentially allocating the data bits of the outputted packet according to a determined number of frames per second; a variable transmission speed transmission unit for transmitting the generated variable frame to a ground communications device at a variable transmission speed according to the determined number of frames per second; and a control unit which determines the number of frames per second based on the amount of data outputted from the packet multiplexing unit and controls the variable frame generation unit and the variable transmission speed transmission unit to select the determined number of frames per second.
