摘　　要：随着网络带宽的剧烈增长和对服务质量的要求不断提高,密集波分复用技术(DWDM)和全光网络正成为研究的热点。通过在一条光纤上传输多个波长的光信号,DWDM能够极大提高光网络的传输能力。在全光网络中,信息的传输和处理都是在光域中进行的。本文对近期的DWDM和全光网络的研究进行了回顾,特别关注了以IP over DWDM为基础的光因特网的进展。Given the extensive growth in Internet traffic and increasing emphasis on service quality, the Dense Wavelength Division Multiplex (DWDM) technique and all-optical network is becoming a hot issue on study. DWDM can greatly increase the information carrying capability of optical networks by transmitting multiple wavelengths on the same fiber. And in all optical network, transmission and processing of the data are carried on in optical field. In this paper we have an overview of the recent development on DWDM tech and the all-optical network, and the evolution of IP over DWDM-based optical Internet is especially depicted.
