四无特性可重构光分插复用器节点设计与测试

Design of and Test on Colorless,Directionless,Contentionless,and Gridless ROADM Nodes

针对光网络的智能化发展需求,在自主研制的1×9可变带宽波长选择开关的基础上,设计了一种多维ROADM(可重构光分插复用器)节点,并采用两种固定带宽波长的信号(10Gbit/s和1Tbit/s)对该节点的各项性能进行了测试。实验结果表明:该ROADM节点具备无向、无色、无阻塞和无栅格等四无特征。

In response to the demand for the development of intelligent optical networks,a multi-dimensional Reconfigurable Optical Add/Drop Multiplexer (ROADM)node is proposed on the basis of the independently developed 1 × 9 tunable band-width wavelength selective switch in this paper,and the related tests are conductedon its various performancesby using signals at two fixed bandwidth wavelengths,i.e.10 Gbit/s and 1 Tbit/s.The test results show that this ROADM node is colorless,di-rectionless,contentionless,and gridless.
