The electro-optical module has a substrate with a mounting surface that is free from depressions. A surface-mounted component unit is disosed on the mounting surface. The component unit contains as integral components an electro-optical component and a lens which are aligned directly with one another. The surface serves, furthermore, as a reference plane for assembling a receptacle for an optical fiber plug.

Electro-optical module

On a front side, a module has a coupling socket for holding an optical fiber end, and at a rear side the module has a holding region in which an electrooptical component is fixed. A joint gap, filled with an adhesive, between the component and the holding region extends in a plane which is oriented perpendicular to the longitudinal axis of the coupling socket. The component and/or the holding region is provided with openings, which lead to the joint gap and taper toward the joint gap, and are introduced into the adhesive.

Electrooptical module

A module has on a front side a coupling socket for holding an optical fiber end, and at a rear side has a holding region for an electro optical component. The component is firstly prefixed in a position of maximum optical coupling by optical irradiation of an adhesive that can be cured both by light and by heat. After the prefixing, a permanent connection is made by thermal curing the adhesive in a temporally and/or spatially separate subsequent production step.
