ABSTRACT:
A device for coupling an incoming light conducting fiber cable to an outgoing light conducting fiber cable characterized by a pair of housings connected together and each receiving a holder which holders center the fibers in one cable in relation to the fibers of the cable which is centered by the other holder. The improvement comprises the holder includes a substrate having a first guide foil disposed on one surface and a second guide foil disposed on the opposite surface, each of said foils having aligned channels for receiving light conducting fibers with the channels of the first foil in a direction leading away from the substrate possessing a cross-sectional profile, decreasing to the diameter of the light conducting fibers. In one embodiment of the invention, the channels are apertures which are aligned with apertures or bores in the substrate and a modification of this embodiment includes forming the first guide foil of a plurality of layers with each layer having apertures converging towards the outer surface thereof with the outermost layer having the smallest aperture. In another embodiment, the channels in the first and second guide foils are arranged as perpendicular channels which extend beyond the peripheral surface of the substrate and, preferably, the light conducting fibers received in the channels are secured on the periphery of the substrate.
