摘　　要：文章比较了目前应用于粗波分复用(CWDM)系统的各类光纤的性能,结合光纤在系统测试中的表现情况对各类光纤的优缺点进行了评价。肯定了标准单模光纤和非零色散位移单模光纤应用于CWDM系统的可靠性,分析了G.652C/D和G.655B/C两类低水峰光纤支持全频谱CWDM传输的优势和在网络升级中的应用潜力,同时与色散位移单模光纤、负色散(平坦)光纤等非主流光纤的性能作了比较。The performances of different types of fibers used in current CWDM systems are compared and their advantages and disadvantages evaluated on the basis of the experimental data from the system tests. The reliability of the applications of both standard SMF and NZ-DSF in CWDM systems is confirmed, the superiorities of two types of low-water-peak fibers G. 652C/D and G. 655B/C in supporting full spectrum CWDM transmission and their potential applications in future network upgrade analyzed and their performances compared with those of the dispersion-shifted fiber, negative dispersion （flattened） fiber and other non-principal fibers.
