Applications of Multiconductor Transmission Line Theory to the Prediction of Cable Coupling. Volume 8. Prediction of Crosstalk Involving Braided-Shield Cables
Abstract
The contents of this report are concerned with the electromagnetic coupling (crosstalk) between braided-shield cables. The effect of pigtails (exposed sections of braided-shield cables in which the shield is stripped back exposing the interior wire) on crosstalk was investigated. It was found that even though the length of these exposed sections constitutes only a very small fraction of the total line length the dominant coupling to the shielded cable can occur via these pigtail sections. If the pigtail sections are eliminated, an additional reduction in crosstalk of as much as 30dB may be realized. The modeling and prediction of this crosstalk was also investigated. A low-frequency model provided accurate predictions for electrically short lines. The multiconductor transmission line (MTL) model was also formulated. The MTL model provided predictions within 1-3dB for electrically short lines and within 6-10dB when the line was electrically long.
