ActiveCoaxial communication cables—Part 1-112: Electrical test methods—Test for return loss (uniformity of impedance)
同轴通信电缆 第1-112部分：电气试验方法 回波损耗(阻抗一致性)试验
Application Summary AI generated
This standard specifies the test method for measuring return loss to evaluate the uniformity of characteristic impedance along coaxial communication cables. It is applied in the telecommunications industry for quality control and performance verification of cables used in high-frequency signal transmission, such as in broadcasting, data networks, and mobile communication base stations. The test ensures minimal signal reflection and impedance mismatches, critical for maintaining signal integrity in RF and microwave systems.
