Lensed fiber optic ferrule with simplified molding
A fiber optic ferrule has a main body with a top surface and a bottom surface and extends between a front end and a back end. The front face includes a recessed portion with a plurality of optical lenses. The front face is configured to allow for the plurality of lenses to be on an angle relative to the front face and the fiber optic ferrule will have not any undercuts and allow the fiber optic ferrule to be ejected from a mold without engaging any portions of the mold.
