ABSTRACT:
A module for a fiber optic data transmission system which will accommodate either a suitable light source or a photoelectric detector. The module incorporates an integrated electronic assembly, such as a hybrid microelectronic assembly. The assembly has provision for a photoelectric transducer which preferably has a cylindrical mount disposed in a cylindrical recess of the electronic assembly. The entire assembly may be surrounded by a cylindrical can having a transparent window. The transducer is provided with a collimating lens which permits it to receive or emit a collimated light beam. Between the fiber optic bundle and the transducer, there is preferably disposed a focusing lens. The focusing lens receives or emits the collimated light beam and focuses it on the fiber optic bundle. A housing surrounds the entire module. Means, such as a retainer ring, are provided for holding the electronic assembly within the housing. Similar means are provided for maintaining the focusing lens within the housing. The distance between the focusing lens and the optical bundle is established by means of a ferrule which in turn is urged toward the housing by a nut and threaded sleeve portion.
