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。

Abstract

Wavelength Division Multiplexing (WDM) devices

as one of the core components of 5G 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 5G 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 5G 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.
