摘要
本文采用商用双向拉曼放大器和附加的辅助激光器，实现了8 × 100 Gbit/s 463 km (76.9 dB)光传输网络的应用实例。对商用拉曼放大器中辅助激光器的位置进行了实验比较和优化。结果表明，与不加辅助激光相比，加辅助激光前后方向的功率预算分别增加了7.3 dB和10.2 dB。结果还表明，在没有远程泵浦放大器的情况下，前向二阶拉曼放大器是一个很好的选择。
Performance improvement in high speed optical networks with low cost amplifier configuration
In this paper, the application example of 8 × 100 Gbit/s over 463 km (76.9 dB) optical transport network is realized by using commercial bidirectional Raman amplifier and additional auxiliary laser without any remotely pump amplifier. The positions of the auxiliary laser in the commercial Raman amplifier are compared and optimized experimentally. The results show that 7.3 dB and 10.2 dB more power budget is obtained with the auxiliary laser in the backward direction and forward direction respectively comparing to the situation without any auxiliary laser. The results also show that forward second order Raman amplifier is a good choice in the condition without remotely pump amplifier.
期刊介绍：
The Journal of High Speed Networks is an international archival journal, active since 1992, providing a publication vehicle for covering a large number of topics of interest in the high performance networking and communication area. Its audience includes researchers, managers as well as network designers and operators. The main goal will be to provide timely dissemination of information and scientific knowledge.
The journal will publish contributed papers on novel research, survey and position papers on topics of current interest, technical notes, and short communications to report progress on long-term projects. Submissions to the Journal will be refereed consistently with the review process of leading technical journals, based on originality, significance, quality, and clarity.
The journal will publish papers on a number of topics ranging from design to practical experiences with operational high performance/speed networks.
