Analysis and modelling of structured wiring communication channels
The authors present equations for the calculation of the attenuation constant of both unshielded and shielded cables as a function of cable dimension, material parameters and frequency of operation. An analytical approach is given for calculating the return loss of a communication channel as a function of such parameters as impedance, length and propagation constant. A transmission-line matrix (TLM) method to assess the effects on attenuation and return loss of longitudinal variations along a structured wire cable is developed. Results are presented using both analytical and modelling approaches; these are validated against measurements.
The research underpinning this paper was funded by over £150k from Brand-Rex Ltd (contact email@example.com), who further supported research in communication cables by over £200k. This paper led to collaboration with Dr Jorg-Hein Walling (firstname.lastname@example.org), head of the Canadian Delegation to the IEC) which has resulted in several conference papers to date. This paper was a major contributor to invitations to deliver tutorials on cable design at the International Wire and Cable Symposium (www.iwcs.org in 2002 – 4) and to invitations to join the TIA’s Balanced Modeling Working Group and BSI committee TC7/-/1.
