摘　　要：从5G室内数字化系统的技术指标出发,分析了传统DAS系统相对室内数字化系统在面向5G部署方面的劣势,得出了数字化系统是5G室内分布系统的主流技术的结论,同时分析了传输线缆的选择成为5G室内数字化系统的关键技术;通过对室内数字化系统传输能力、供电要求以及不同线缆的传输与供电能力分析,得出CAT6A网线或光电复合缆将是5G室内数字化系统的选择方案,最后通过分析传输线缆部署实例,给出了线缆选择的建议。With the introduction of 5G indoor digital system’s technical indicators,the disadvantage of traditional DAS contrasted with DIS had been introduced,and the conclusion that the DIS is the mainly technology of 5G indoor coverage system had been given.At the same time the selection of transmission cables will be the key technology in the 5G indoor DIS.By analyzing the transmission ability and power supply requirements of indoor DIS,the transmission and power supply ability of difference transmission cables,the conclusion that the CAT6A cable or optical and electronic composite cable will be the selection scheme of 5G indoor DIS is put forward.Finally,through the analysis of the deployment examples of transmission cables,the selection proposals of transmission cables had been gave.
