Design and Performance Review of Optical Static Wire "a Second Generation"

Optical Static Wire has become a widely-used means of providing optical communication links along utility right-of-ways. Our initial concept consisted of a welded aluminum pipe, which provided physical and environmental protection for the optical fibers contained therein. This paper presents the results of the development of a helically channelled solid aluminum core construction for the positioning of loose buffered optical fibers. This second generation cable design eliminates many of the disadvantages encountered with the first generation design. The technical features of the loose buffer tube design and performance characteristics of the completed cable are discussed.
