摘　　要：文章针对光纤放大器在长距离传输中面临的信号衰减、增益不平坦、色散效应及非线性效应等问题,提出了一套系统优化方案。通过多目标优化的光纤链路设计、双泵浦双向抽运的增益均衡技术、混合色散补偿方案以及数字背向传播非线性补偿算法等措施,显著提升了系统传输性能。实验结果表明,优化后的系统在各项关键性能指标上均取得显著改善,包括光信噪比、误码率、眼图张开度等,验证了所提出优化方案的有效性和实用性。In this paper,a system optimization scheme is proposed to solve the problems of signal attenuation,gain uneven,dispersion effect and nonlinear effect faced by optical fiber amplifiers during long-distance transmission.The transmission performance of the system is significantly improved by means of multi-objective optimization of fiber link design,gain equalization technology of dual-pump bidirectional pumping,hybrid dispersion compensation scheme and digital backpropagation nonlinear compensation algorithm.The experimental results show that the optimized system has achieved significant improvement in various key performance indicators,including optical signal-to-noise ratio,bit error rate,eye pattern spread,etc.,which verifies the effectiveness and practicability of the proposed optimization scheme.
