摘　　要：波分系统速率的每一次提升,都会受到衰耗、CD、PMD及非线性效应等引起的传输损伤的限制,因此迫切需要更为先进的技术来减小这些传输损伤带来的影响,从而解决系统速率和传输距离受限的问题。本文主要介绍了100 Gbit/s波分技术的发展现状、关键技术,并对未来的推进策略提出了建议。Once the rate increase,the DWDM system would be limited by the transmission impairments that caused by attenuation,CD,PMD and nonlinear effects.There is an urgent need for more advanced technology to reduce the impact of these transmission impairments,so as to solve the systemrate and the transmission distance is limited by the problemes.This paper mainly introduces the current developing condition and key technique of 100G DWDM,and makes some suggestions for future strategy to carry out.
