| 摘要: |
| 针对一个超长距OTN光传送网传输案例，我们设计了不同的放大器配置方案并进行了实验研究。通过实验，我们发现使用双向拉曼放大器的配置方案或者使用遥泵放大器的配置方案，都可以完成传输任务，但是系统传输余量比较小。而使用拉曼加遥泵放大器的配置方案则可以得到更多的功率裕度和更高的输出信噪比，而且价格适中。 |

| Abstract: |
| Aiming at a long haul OTN (optical transmission network) transmission system, we design different amplifier configuration scheme and make an experimental study. We can realize 350km unrepeated system with bidirectional Raman amplifier scheme or remotely pumped EDFA scheme, but the power margin is very small. Using Raman amplifier plus remotely pumped EDFA scheme, we can get more power margin and high OSNR and better price performance ratio. |
