光分插复用器 (OADM)是实现波长上下话路、灵活配置网络资源的关键网元设备之一 .因为阵列波导光栅 (AWG)在成本和综合性能方面具有很大的优越性而使其成为目前最适于作为 WDM复用器与解复用器以及构成 OADM的关键器件 .文章详细研究了基于AWG构建 OADM的不同结构组成 .主要研究了环回和折叠型两种结构 ,并给出了易于实现集成的平板形结构设计的不同方案 .
Optical add / drop multiplexer (OADM) is one of the key network element devices to realize wavelength channel and flexibly configure network resources.As Array Waveguide Grating (AWG) has great advantages in terms of cost and overall performance, And become the most suitable device for WDM multiplexer and demultiplexer and the key device for OADM.The paper studies in detail the different structure components of OADM based on AWG.It mainly studies the two structures of loopback and fold type, Easy to implement integrated flat-panel structure design of different programs.
