摘要

This paper presents an effective solution for the crosstalk prediction of hand made cable bundles. The outer- and inner- layer topology of the cross section are analyzed respectively, combined with the actual physical model of the cable bundles. The cascading method is used to deal with the relationship between the structure of cable bundles and the distributed per unit length (p.u.l.) parameter matrices. The random exchange of the wires in the cable bundles is equivalent to the row-column transformation of the p.u.l. parameter matrix, and the values of the p.u.l. parameter matrix after the transformation are modified by equal interval rotation degree. Then, the unconditionally stable finite difference time domain (FDTD) method is used to solve the crosstalk. The verification analysis shows that the change of the element value of the p.u.l. parameter matrix caused by the rotation of the cross section relative to the ground can not be ignored. The accuracy of the proposed method is evaluated through comparison to the probability method for a seven-core hand made cable bundles, especially in the high frequency.
