What is Fitting

This chapter is an updated, enhanced, and expanded paper previously published in IJMMME. An attenuation-based mathematical model and computational tool for communication cable design is presented in the chapter. The relationship derived for the model creation connects attenuation with the following parameters of cable design and testing: copper wire, aluminum and insulation thicknesses, cable impedance, test frequency, and lay length. The expression found from numerous measurement data was used to simulate the Monte Carlo prediction of attenuation in the cable. To realize the simulations, a life script and regular MATLAB script programs were developed. The programs produce a special graphical user interface suitable for non-programmers, cable engineers, and technicians. Results of calculations obtained with the developed tool were verified by experiments and indicate that the tool can be used to design cables with optimal parameters.
