EMC parameters of single-pair Ethernet cables

In this paper, LFCA is placed in the framework of the usual procedures for evaluating shielding properties and compared with simulation calculations. The results of a “Round Robin Test” of symmetrical single-pair cables are compiled. Furthermore, the suitability of the LFCA measurement method for assessing the shielding effectiveness of unshielded balanced cables is discussed, since the mentioned standards for single-pair cabling and cables also include unshielded constructions.
