A novel RS(255,239)+BCH(3860,3824) concatenated code with 7.70% redundancy for long-haul optical transmission systems is constructed and analyzed through the theoretical analysis of the relevant concatenated code. The simulation analysis shows that the novel concatenated code, compared with the RS(255,239)+CSOC(k0/n0=6/7,J=8) code in ITU-T G.75.1, has a lower redundancy and better error-correction performance. In addition, the net coding gain (NCG) of the novel concatenated code is respectively more 0.44dB and 0.47dB than that of BCH(3860,3824)+ BCH(2040,1930) code and RS(255,239)+CSOC(k0/n0 =6/7, J=8) code in ITU-T G.75.1 at the third iteration for the bit error rate (BER) of 10-12. As a result, the novel concatenated code can be better suitable for long-haul optical transmission systems.
