Abstract
A system for coupling a transmit fiber and a receive fiber to a light source and a photodetector, respectively, includes a unitary clear plastic member having lenses and total internal reflection (TIR) mirrors which cooperate to provide propagation along perpendicular X, Y and Z axes. The light source, photodetector and unitary optical member are surface mounted to a printed circuit board having drive circuitry for the light source and processing circuitry for the photodetector. By enabling surface mounting of the detector and light source, the cost of fabrication is significantly reduced.
