Abstract : The proposed IBM Local Area Network architecture required a cable consisting of two twisted pairs. The paper describes the design and construction of a cable to meet the required parameters of attenuation, crosstalk and characteristic impedance. The cable which resulted from this design has been characterized from 10 kHz to 20 MHz, and is capable of sustaining both low and high speed data transmission over this entire frequency spectrum. Detailed curves showing the major parameters as a function of frequency for typical samples are presented. In addition, versions of the cable have been designed to meet U.L. requirements for both plenum and non-plenum use. (Author)
