1. A method for check information block coding in 10 gigabit per second Ethernet passive optical network (EPON), comprising:

  • adding a synchronization header to each of a plurality of data information blocks, wherein the synchronization header comprises a bit indicating an information type of the corresponding data information block;

    performing a forward error correction (FEC) coding on a predetermined number of the data information blocks and the bits in the synchronization headers associated with the data information blocks to generate M continuous check information blocks following the predetermined number of the data information blocks;

    adding a synchronization character to each of the M continuous check information blocks according to a synchronization character sequence {Tj}, wherein one check information block with one synchronization character comprises 66 bits, wherein the synchronization character is used for synchronization of the check information blocks and the synchronization character is “

    00”

    or “

    11”

    , wherein the synchronization character added to a jth check information block Pj is Tj, and the synchronization character sequence {Tj} satisfies the following conditions;
