Abstract

We report the experimental comparison of 10.7-Gb/s duobinary transmissions using generic Reed-Solomon forward error correction (FEC) and an enhanced FEC. The coding gains of the two FECs after transmission over a dispersion-uncompensated 200-km standard single-mode fiber (SSMF) link are found to be much larger than those quoted in ideal case, with the enhanced FEC further outperforming the generic FEC by /spl sim/3.5 dB. Numerical simulations show reasonable agreement with the experimental results.
