基于DWDM的分布式全光网络的实现研究

Research of DWDM-based distributed AON construction

全光网即网络中所有节点之间信息的传输和交换始终保持光的形式,它可以有效地解决光电转换器件的"电子瓶颈"问题,提高光通信容量。从实现的角度探讨了全光网的构建问题,从光传输、光器件、光交换及光信号处理等方面进行了分析。在现有光交换理论和器件条件下,提出了基于DWDM技术、以光路交换为核心的分布式全光网络的构建方案。

All-optical network that the information＇s transmission and exchange between the nodes are always keep in the form of light,it can effectively solve the＂electronic bottlenech＂problem of electron converter,to improve the optical communications capacity.This paper discuss the AON＇s construction in view of realizes.And it is analyzed form optical transmission,optical devices,optical switching and optical signal processing technology.Under the conditions of the existing optical switching theory and devices,to propose a distributed all-optical network construction solution that based on DWDM technology and the optical circuit switching as the core.
