A forward error correction method including inserting at least one filler symbol into an input data stream at a pre-determined position, thereby generating a precoded symbol group, FEC encoding the precoded symbol group, thereby generating a code word, removing at least one of the filler symbols from the code word, thereby generating an optimized code word, inserting at least one filler symbol into the optimized code word at the predetermined position, thereby generating a deoptimized code word, FEC decoding the deoptimized code word, thereby generating a decoded symbol group, and removing at least one of the filler symbols from the decoded symbol group, thereby generating an output data stream.
