新型大容量光交换的关键技术和应用

High-Optical Switching and Its Applications

为了实现更大容量的光交换,需要突破矩阵光开关的规模化"瓶颈"。微机电光开关(MEMS)、循环阵列波导光栅(CAWG)、波长选择开关(WSS)等具有多端口规模化特征,能够实现良好的模块化扩展,具有使交换容量倍增的潜力。MEMS、CAWG、WSS在大型数据中心、大容量光交叉连接、灵活栅格光分插复用等系统的应用中具有独特优势和良好前景。

To achieve high-capacity optical switching, the optical switch matrix needs to be investigated. The micro-electromechanical system （MEMS） switch, cyclic array waveguide grating （CAWG）, and wavelength selective switch （WSS） have the advantages of multiport dimensions and expansibility to a larger modular scale. They have potential applications in data center network, optical cross-connect, and flexible gridless optical add-drop multiplexer.
