ABSTRACT:
An optical fiber coupler including an optical fiber having an end, and an electronic light pulse communication assembly comprising an assembly housing, an electronic light pulse communication device fixed within the assembly housing, and a lens mounted on the assembly housing and in light pulse communication with the electronic light pulse communication device. The optical fiber coupler also includes a coupler housing having an inlet well, an assembly well separated from the inlet well by a coupler housing wall and having the assembly fixedly received therein, and a fiber passage which extends between the inlet well and the assembly well and which snugly receives the fiber so that the fiber end is adjacent the assembly lens. The coupler housing further includes epoxy in the inlet well so that the fiber is secured to the coupler housing, and index matching gel surrounding the optical fiber end to assembly lens junction so that substantially all of the light passing between the assembly lens and the fiber does not escape from the optical fiber end to assembly lens junction.
