ABSTRACT OF THE DISCLOSURE An optical fiber coupler for interfacing with a light active element and means for assembling and connecting said coupler to said element. The coupler comprises a guide assembly having at least three glass rods disposed in a side- by-side array, parallel to one another and with longitudinal peripheral portions of adjacent rods in contact and connected to each other to form a cusp-shaped interstitial channel there- between. The assembly includes a first and second flat end. The channel at the second end is flared to facilitate the ingress of an optical fiber in said channel. A segment of optical fiber having a first and second flat end is disposed and fused within the channel with its second end located at an intermediate portion along the channel with its first end being co-planar with the first end of the guide assembly. m e light active element, such as a light emitting diode, is secured to the first end of the optic fiber section and the co-planar end of the guide assembly to form a good light transmissive interface. -1-
