摘　　要：波分复用(WDM)器件作为第五代移动通信(5G)前传网络的核心组成部件之一,近年来发展迅速。前传网络对WDM相关器件、组件和产品等提出了新的要求,但当前5G前传网络用WDM器件的技术要求和测试方法标准尚未明确,文章通过深入分析WDM器件测试过程中遇到的问题,提出了5G前传网络用WDM器件测试方法,并构建了相应的测试系统,与手动检测方式对比,具有很好的一致性,效率是手动测试的10倍以上。Wavelength Division Multiplexing(WDM)devices,as one of the core components of 5 G fronthaul network,have developed rapidly in recent years.The fronthaul network has proposed new requirements for WDM devices,components and products.However,the technical requirements and test method standards of WDM devices for 5 G fronthaul network are not clear.Through in-depth analysis of the problems encountered in the test of WDM devices,we propose a test method of 5 G fronthaul WDM devices,and build the corresponding test system,which is compared with the manual test method.The results show that the proposed test method has 10 times more efficient than manual test method with good consistency.
