摘要
从光插/分复用器(OADM)的设计原则入手,对现有的光插/分复用器进行了总结和比较,按照结构特点将其分为6类基本形式:基于声光可调谐滤波器(AOTF)的OADM,基于磁调谐FBG的OADM,基于波长光栅路由器(WGR)的OADM,分波器+空间交换单元+合波器型OADM,耦合单元+滤波单元+合波器型OADM,基于模间耦合的全光纤型OADM。论述了各类OADM的结构,工作原理,性能特点,对OADM的发展前景进行了展望。
Current OADMS （optical add/drop multiplexers） are summaried and compared based on the rule of design. According to their structures, all of them are classified to 6 types：OADM based on AOTF （acoustic optical tunable filter）, OADM based on magnetic tunable FBG （fiber Bragger grating）, OADM based on WGR （wavelength grating muter）, OADM based on division multiplexing element, wavelength switching element and multiplexer, OADM based on coupling element, filtering element and multiplexer, all - fiber OADM based on mode coupling. The operational principles, configurations, characteristics are generally described. The future development of OADM is forecasted.
