摘　　要：文章从业务发展的需求出发,详细讨论了可重构光分插复用器(ROADM)设备的优点,提出了一种基于波长阻塞器(Wavelength Blocker,WB)的ROADM实现方案,并针对实际应用测试了该ROADM节点设备的最大光信噪比(OSNR)代价。结果表明这种ROADM节点设备满足应用的需求。In view of the requirements for service growth, this article discusses in detail the advantages of ROADM device, presents a realization scheme for Wavelength Blocker （WB）-based ROADM and measures the maximum OSNR penalty of this ROADM node device in relation to its practical applications. The results indicate that this device meets the requirements in applications.
