ABSTRACT:
An alignment and retention device for optical transmission fibers having an optical lens with a forwardly directed curved surface molded to a rearward extension. The extension has an upper portion and a lower portion separated by a vee-shaped gap, each portion having a longitudinally extending vee-shaped groove for aligning and supporting an optical fiber. The lens and rearward extension are fashioned from a single piece of plastic with an abutment means comprised of a vertical stop at an interface therebetween. A focal point of the lens is located at the abutment means and a retention means securely retains the optical lens while a clamping means surrounds the retention means forcing the upper and lower portions together for capturing the optical fiber within the vee-shaped gap providing forward and lateral fiber alignment without using an index matching adhesive.
