ABSTRACT:
An electro-optical module for facilitating connection between a fiber optic cable connector and an electrical circuit includes an interlocking tongue-and-groove design between the skirts of the module and an electro-optical active device. Within the electro-optical active device, a lens provides hermetic sealing to the case so as to eliminate the requirement for an additional window. A barrel providing partial enclosure for the lens is used to facilitate alignment with the fiber optic cable. Finally, the total module includes mechanisms so that exact spacing is obtained between the light source and the end of the fiber optic cable whereby the beam waist of the light when the device is used in the transmission mode occurs interior to the cable rather than at the surface to accommodate manufacturing tolerances, bending forces and to reduce noise generated by reflections, etc.
