description The invention provides a cable measurement method and an indoor distributed antenna system, which are applied to a 5G NR communication system, and the 5G NR communication system is connected with a remote radio unit (RRU) and a plurality of distributed antenna units (DAU) by using a plurality of multi-pair cables. The cable measurement method comprises the following steps: measuring characteristic impedance of multiple pairs of cables through a network analyzer; measuring the insertion loss of multiple pairs of cables through a network analyzer; measuring far-end crosstalk of a plurality of pairs of cables through a network analyzer; and measuring near-end crosstalk of multiple pairs of cables by a network analyzer. According to the invention, measurement of multiple pairs of cables connected with the RRU and the DAU in the 5G NR communication system can be realized. 本申请提供一种电缆测量方法以及室内分布式天线系统，应用于第五代新无线5G NR通信系统，5G NR通信系统使用多条多对电缆连接远端射频单元RRU和多个分布式天线单元DAU。所述电缆测量方法包括：通过网络分析仪测量多对电缆的特性阻抗；通过网络分析仪测量多对电缆的插入损耗；通过网络分析仪测量
