This paper focuses on a certain class of signal transmission system designs and presents the results of parametric studies to illustrate the comparative cost of hard-wire and fiber optic transmission media.

Abstract

Traditional design of intrusion detection systems has relied upon proven hard-wire communication links, however, there are inherent difficulties in these systems. The first difficulty is that the hard-wire cables must be physically separated and/or shielded from the AC power bus. Secondly, when large distances are involved, significant overdesign is often dictated to accommodate signal attenuation. In certain circumstances, the use of fiber optic transmission media can be a cost-effective solution to these problems. 4 figures, 2 tables. (Author abstract modified)
