ABSTRACT:
A distributive coupler for use with at least one set of optical fibers includes a fiber optic terminal for supporting the end portions of each set of optical fibers. In a reflective mode, the coupler is adapted for use with one set of optical fibers by directing light transmitted through any one or more of the optical fibers back onto the set of optical fibers. A reflecting element is utilized to reflect transmitted light toward the set of optical fibers and a focusing element is utilized to focus reflected light onto the set of optical fibers. In a transmissive mode, the coupler is adapted for use with two sets of optical fibers by directing light transmitted through any one or more of the optical fibers onto the other set of optical fibers. A shaping element is utilized for shaping light transmitted toward the other set of optical fibers and a focusing element is utilized for focusing transmitted light onto the other set of optical fibers. The coupler also includes telescoping housing segments for adjusting the position of the optical elements relative to each fiber optic terminal. With these features of construction, the distributive coupler produces substantially uniform illumination of all of the optical fibers of a set of optical fibers.
