通过对科技文献的归纳总结和分析比较 ,介绍了四种实现双向波长上下路的光分插复用器结构和工作原理 ,它们是 :( 1 )基于 FBG和多口光环形器 ;( 2 )基于波导光栅路由器和FBG;( 3)基于阵列波导光栅 ( AWG) ;( 4 )基于解复用器 /复用器对和光开关的

This paper summarizes and compares four kinds of bidirectional wavelength optical add drop multiplexers (OADMs) based on some technique papers. We introduce the principles and structures of them. They are (1) OADM using FBGs and multiport optical circulators; (2) OADM using waveguide grating routers and FBG; (3) OADM using AWG; (4) OADM using DMUX/MUX and optical switchs.
