摘　　要：为了确保高速光通信网络的传输质量,必须对光链路回波损耗实现有效控制。通过对光链路回波损耗产生机理的分析,主要测量方法(光连续波反射法和光时域鉴别反射法)的对比,以及单模FC/PC跳线多级互连光链路和MT光缆组件多级互连光链路的回波损耗实测评估,发现在多级互连情况下光链路回波损耗存在叠加降低现象。相关研究结果对后续提升多级互连光链路回波损耗有一定的参考意义。In order to ensure the transmission quality of high-speed optical communication networks,it is necessary to effectively control the return loss of optical links.By analyzing the mechanism of the return loss in optical links,comparing the main measurement methods(optical continuous wave reflection method and optical time-domain discriminant reflection method),and evaluating the return loss of single-mode FC/PC jumper multistage interconnected optical links and MT optical cable assembly multistage interconnected optical links,it has been found that there is a phenomenon of superposition decreases in the return loss of optical links under multistage interconnection.The relevant research results have certain reference significance for improving the return loss of multistage interconnected optical links in the future.
