  • Optical fiber cable and method of making the same
    Patent number: 4953942
    Abstract: A spacer-type optical fiber cable has a rod-type spacer which includes closed spaces for holding corresponding optical fibers within these closed spaces. The closed spaces of the rod-type spacer are formed from open straight grooves on a flat-type spacer and then transforming the flat-type spacer into a circular rod-type spacer during a sequence of manufacturing steps, one step using a tapered die to perform the spacer transformation.
