Abstract:
The results from an experimental study of crosstalk interference between twisted pairs of conductors of an electrical wire bundle model are presented. The aim of the study is to determine the crosstalk interference levels in a shielded twisted pair of conductors when there is heterogeneity in the form of a gap between the shield of bundle conductors and the electrical connector body. The studies were carried out on the electrical wire bundle mockup consisting of shielded and unshielded twisted pairs of conductors. The unshielded twisted pair of conductors was used as a source of crosstalk interference. The shielded twisted pair of conductors had a gap between the shield of conductors and the electrical connector body and was a receptor for the crosstalk interference. To study the crosstalk interference levels, the gap length of the shielded twisted pair of conductors was varied. As a result of the study, the crosstalk interference levels for gaps of different lengths were determined. The effect of an electrically conducting connection made using a jumper in the gap between the shield of a twisted pair of conductors and the electrical connector body of the electrical wire bundle mockup on the crosstalk interference levels was studied. A comparative analysis of the results obtained from measurements of the crosstalk interference levels in a shielded twisted pair of conductors with heterogeneities in the form of gaps of different lengths with the crosstalk interference levels in a shielded twisted pair of conductors with a homogeneous shield is carried out. A conclusion about the need to ensure connection of the shields of electrical bundle conductors with the bodies od electrical connectors without gaps has been formulated.
