摘　　要：目前中国5G通信前传网络采用波分复用(WDM)技术方案,有效解决了光缆铺设和空间占用等资源浪费困扰。根据设计方案需求6波、12波及18波无源合波/分波器,而针对无源波分器件,从其体积尺寸和光学参数两方面进行对比,说明多通道紧凑型波分器件(CCWDM)都优于多个器件串接方式。其中光纤准直器是必不可少的光纤零部件,尤其是多通道长距离的应用场景,因此设计出性能优、成本低的光纤准直器变得尤为重要。本文从理论设计到实际制作对光纤准直器做了详细指导,阐述了高斯光束传播q参数及ABCD矩阵,可为专业技术人员及专家学者提供使用数据。At present,China's 5G communication fronthaul network adopts wavelength division multiplexing technical solutions,which effectively solves the problem of resource waste such as optical cable laying and space occupation.According to the requirements of the design plan,6-wave,12-wave and 18-wave passive multiplexer/demultiplexer,and for passive wavelength division devices,the comparison of their size and optical parameters shows that the multi-channel compact wavelength division device are better than multiple devices in series.The optical fiber collimator is an indispensable optical fiber component,especially for multi-channel and long-distance application scenarios.Therefore,it is particularly important to design an optical fiber collimator with excellent performance and low cost.This article provides detailed instructions for the optical fiber collimator from theoretical design to actual production,expounds the Gaussian beam propagation q parameter and ABCD matrix,which can provide professional technical personnel and experts with the use of data.
