摘要
利用双向抽运拉曼放大器实现了4×100Gbit·s^(-1)光网络传输295km(68.85dB)的应用,测试了系统的光学信噪比、传输余量及长期误码特性,仿真了双向抽运拉曼放大器在4×100Gbit·s^(-1)传输系统中的功率演化过程。研究结果表明,双向抽运拉曼放大器的应用需综合考虑信号输入功率、前后向拉曼增益及经济成本等。
An unrepeated transmission system of 4×100 Gbit·s^-1 over a span loss of 68.85 dB is realized by the bi-directionally pumped Raman amplifier (BDPRA) scheme. The optical signal to noise ratio, transmission margin, and bit error ratio of this system are tested. The power evolution of this BDPRA in the 4×100 Gbit·s^-1 transmission system is simulated. The research results show that the signal input power, forward/backward Raman gain distribution and cost should be comprehensively considered in the applications of the BDPRA scheme.
