Abstract: We have developed a simulator that accurately predicts OSNR and Q of Raman assisted transmission systems. It was validated in 16 x 12.3 Gbis/s recirculation loop transmission experiment over 7500km utilizing 90km spans. We demonstrated Q values with an average margin of 5.7 dB over FEC limit with 23% overhead.
