We report the experimental demonstration of a 10.7-Gb/s duobinary transmission using both generic Reed-Solomon forward error correction (FEC) and an enhanced FEC. The coding gains of the two FEC's after transmission over a dispersion-uncompensated 200-km SSMF link are found to be much larger than those quoted in the ideal case. Numerical simulations show reasonable agreement with the experimental results.
