Systems and methods for optical communication through air or space are disclosed. A method includes encoding one or more data frames with a data-link layer forward error correction (FEC) code to produce a plurality of encoded data frames and transmitting the plurality of encoded data frames from a transmitter (TX) to a receiver (RX) at least partially through air or space using a plurality of optical beams. The RX identifies a corrupted encoded data frame and reconstructs the corrupted encoded data frame using a data-link layer FEC decoder operating over a plurality of non-corrupted encoded data frames.
