A method of preparing data for transmission. The method includes providing a block of data, generating a plurality of first dimension code words including first dimension forward error correction FEC elements, the elements of each code word may be used interchangeably to reconstruct a data portion of the block corresponding to the code word, defining a plurality of second dimension source words formed of the generated elements and generating for at least two of the defined second dimension source words, different numbers of parity elements.
