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.

    • "CD induces pulse-broadening, causes intersymbol interference, and adds complexity to clock recovery due to the radio-frequency (RF) fading of clock components [4]. Point-to-point uncompensated transmissions have been achieved with prechirping [6], duobinary modulation [7], and forward error correction coding [8]. Cascaded operation of optical 2R regeneration achieved 3600-km uncompensated transmission through single-mode fiber at 2.5 Gb/s [5]. "

    ABSTRACT: We propose an optical 3R regenerator that incorporates a clock enhancement stage based on a semiconductor optical amplifier (SOA)-based Mach-Zehnder interferometer and a 10-GHz all-optical clock recovery module employing a Fabry-Perot filter and an SOA. The experiments assess the optical 3R regeneration technique using a fiber recirculation loop containing 125-km dispersion uncompensated large effective area fiber with a total chromatic dispersion of 531.25 ps/nm. The optical 3R regeneration achieves error-free 125 000-km dispersion uncompensated return-to-zero transmission at 10 Gb/s over 1000 optical 3R stages. The bit-error-rate (BER) measurements show that there is only 1.2-dB power penalty at 10<sup>-9</sup> BER between 125 000-km (Lap 1000) uncompensated transmission and back-to-back using pseudorandom bit sequence 2<sup>23</sup>-1

    ABSTRACT: We demonstrate a receiver, which improves the back-to-back (b-t-b) performance of optical duobinary signals at 10 Gb/s. The required optical signal-to-noise ratio for a bit-error rate of 1×10<sup>-3</sup> was found to be as low as 10.8 dB in b-t-b operation. We tested the receiver with two commercially available 10-Gb/s duobinary transmitter samples. Excellent chromatic dispersion tolerance was maintained with the novel receiver design.
