摘要
为了探究二阶拉曼放大在OTN超长距传输系统中的作用,对8×10 Gbit/s的333.5 km的OTN无中继传输系统进行了理论和实验研究。研究结果表明:与配置一阶拉曼放大器的系统相比,配置二阶拉曼放大器的OTN传输系统可以获得更高的传输指标。运用二阶拉曼放大器配置方案,可以将8信道10 Gbit/s OTN系统传输容限从59 dB提高至66.7 dB,系统平均OSNR为13.03 dB。实验系统与仿真系统采用同样的光学参数,结果表明二者较为吻合。
The application of second-order Raman amplifier in OTN(Optical Transport Network)ultra-long distance transmission system is studied theoretically and experimentally.The research results show that compared with the first-order Raman amplifier,a second order Raman amplifier can achieve its higher gain and lower noise performance.With the second-order Raman amplifier configuration scheme,the transmission power budget of the 8-channel 10 Gbit/s OTN system can be increased from 59 dB to 66.7 dB,and the average OSNR(Optical Signal to Noise Ratio)of the system is 13.03 dB.The theoretical and experimental results are quite consistent.
