中文摘要：
介绍了一种基于光纤光栅波长路由的全光双纤单向自愈环网,环内四节点具有16×10Gbit/s的传输能力.利用啁啾光纤光栅（CFBG）的波长可选择特性,实现了分布式的上下话路和波长选择功能,同时有效地补偿了传输色散.网络管理参照了网络管理协议（SNMP）的网络管理模型,通过对网络的重要参数进行实时监测来控制网络运行.实验结果表明,当环上任一处光缆发生故障时,通信业务能够自动恢复,恢复时间小于50ms,可实现网络的快速自愈,符合ITU-T G.841的建议规定.
英文摘要：
The single-direction, self-healing all optical ring network with double optical fibers based on the wavelength routing character of fiber gratings is introduced. The four-node network with ring topology can provide 16×10Gbit/s optical transmission. The wavelength-selecting character of chirped fiber gratings is used for wavelength routing, and the function of dispersion compensation and multi-channel add/drop is achieved, too. The SNMP（Simple network management protocol） model is referred to manage this network. Some important parameters are real-time observed to control the network. The results show that if any optical fiber in the ring is broken down, the interrupted telecommunication service can be recovered automatically in less than 50ms.
