Title: Two-parallel concatenated BCH super-FEC architecture for 100-GB/S optical communications
Abstract: This paper presents a high-speed Forward Error Correction (FEC) architecture based on the concatenated BCH code for 100-Gb/s optical communication systems. The concatenated BCH code consists of BCH(3860, 3824) and BCH(2040, 1930), which provides 7.98dB net coding gain at 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−12</sup> corrected bit error rate without additive overhead as compared with the Reed-Solomon(255, 239) standardized in ITU-T G.975 and G.709. This architecture has been implemented with 90-nm CMOS standard cell technology in a supply voltage of 1.1V. The implementation results show that the concatenated BCH Super-FEC architecture can operates at a clock frequency of 400MHz and has a throughput of 102.4-Gb/s for 90-nm CMOS technology.
