Practical measure of cable coupling

Abstract

− In this paper the crosstalk between two parallel coaxial cables is investigated. It is shown that the degree of coupling is strongly effected by the geometry of the system. In many practical situations the geometry of the cable routing is ill-defined so that an exact deterministic solution is not possible or helpful. A simple solution based on the first resonant frequency is proposed which can also be used to provide some statistical analysis of the possible degree of cable coupling.

“…which will then induce a current I t on the outer sheath of the victim cable. I t circulates around a circuit composed of the outer sheaths of the two parallel cables and termed the tertiary circuit [21].…”
