As the high-speed data communications such as xDSL using the existing copper cable come into wide use, the electromagnetic coupling characteristics of telecommunication cables become more significant. In order to describe the screening performance of telecommunication cable, the transfer impedance of cable shield is required. This paper describes the transfer impedance for telecommunication cables using the line injection method of IEC 96-1. Results are analyzed to show how the positioning of the injection line and of the inner conductor of the cable under test (CUT) affect the value of transfer impedance and how the transfer impedance is changed with the frequency.
