摘要
介绍了可重构光分插复用器(ROADM)设备实现结构从第一代到第三代和使用技术从波长阻断(WB)器、平面光波导(PLC)到波长选择开关(WSS)的演进过程。给出了基于WSS模块构成的更具灵活性的第三代ROADM,并分析了其"无色"、"无方向性"和"无竞争性"的特点。最后,对三代ROADM各自的应用特点进行了小结。
The development of the ROADM device architecture from the first to the third generation is introduced.The technologies of ROADM such as the wavelength blocker（WB）,Planar Light-wave Circuit（PLC） and the wavelength selective switch（WSS） are presented concisely.Gives the third generation ROADM consisting of WSS module,which is more flexible.This paper analyzes the feature of ROADM,which is＂colorless＂,＂directionless＂ and ＂contentionless＂.Finally,the three generations of ROADM application characteristics are summarized.
