Claim of US Patent No. 10,798,756

8. A method for performing forward error correction of data to be transmitted over an optical communications channel, the method comprising:encoding an arrangement of data bits; the arrangement having rows of blocks including a first row of blocks; wherein each block of the arrangement is enabled to store a plurality of bits; the encoding of the arrangement including:
generating parity bits by applying a first error correcting code to at least some of a first set of data bits in blocks of the first row; and applying the first error correcting code to at least some of a second set of data bits; wherein the second set of data bits is located in a set of blocks; wherein each block of the set of blocks is in a different row than the first row; wherein each respective block of the set of blocks is in a different column and a different row than each other block of the set of blocks; and
storing the generated parity bits in the first row of blocks.
