Abstract
A fiber optic light transfer device has a plurality of optical fibers with first and second end surfaces. A locator body for the first end surface has parallel slots through which the fibers extend and by which the fibers are located and mechanically held against movement relative to one another in three mutually perpendicular planes. The locator body has ear projections along the back as well as a projection and socket for aligning and connecting two locator bodies side by side. The locator body has a series of ridges and grooves along opposite surfaces which enable them to be connected in a columnar arrangement. A separator is disposed between each ribbon for disposing the fibers forming the second end surface in substantially parallel planes. These separators and ribbons are integrally joined by glue to form a matrix body. The matrix body has a series of ridges and grooves which assist in aligning and connecting them side by side and end to end in an assembly. A channel-shaped locator element provides the ridges and grooves and mating surfaces for stacking the elements in a former and forms the locator body.
