摘　　要：文章回顾了近几年高速光纤传输系统出现的新技术,介绍了几种利用先进调制技术的高速光纤传输系统。由于先进的调制技术、电子色散补偿技术和超强纠错技术等一系列新技术的突破和成熟,这就奠定了性价比提高的坚实基础。无论是市场的需求,技术的进步,还是成本的降低、光缆PMD性能的考虑,以40G/100G为基础的WDM系统的应用将是大势所趋。This paper reviews the novel technique for high speed fiber systems in recent years, and introduces several high speed fiber systems using advanced optical modulation formats. Because of the breakthrough and maturities for a series of new technologies such as advanced modulation, electrical dispersion compensation and super FEC, solid foundation has been established for improving the ratio of performance to price. Based on the market demands, technology advances, cost decline and PMD performance of the fiber, the applications of WDM systems base on 40 G/100 G will be the direetion.
