DWDM Reconfigurable Optical Network Test-Bed and Its Management

本文设计集成并演示了一种业务驱动型可重构光网络平台,建立了光网络的固定连接和交换连接,探讨了可变业务网络的可重构流量疏导中的完全适配方案的实现方法,根据业务流量变化的需求,实现了光网络物理结构的重构.根据可重构光网络管理的特殊要求,实现了对该光网络中光网元控制管理和各光波长通道波长稳定性、光信噪比、信道功率、定时抖动、消光比、色散、误码率等性能参数的监控,且该光性能监控方案对数字光信号的协议和速率透明,还解决了动态路由技术条件下实时光功率电平的均衡问题.

A reconfigurable optical network test-bed driven by dynamic traffic is designed,integrated and demonstrated.Permanent connection and switched connection is established. A realizing technique of the full fit scheme in reconfigurable grooming of dynamic traffic is discussed and a kind of the network which structure can be automatically reconfigured according to dynamic traffic is implemen .ted. The remote management to erbium-doped fiber amplifiers and optical cross connect （OXC） and monitor to optical performance of data stream are achieved under the condition of the reconfigurable optical networks. The supervision of the wave- length stability, optical signal to noise ratio, time jittering, extinction ratio and bit error rate （BER） of any optical wavelength channel in the network is realized. The real time channel power equalization is also implemented under the dynamic routing condition.
