A hermetically sealed optical fiber lens arrangement, particularly for optoelectronic modules, includes an optical fiber which extends through a metal tubule and is fastened therein. The metal tubule is attached through a flange at an aperture in a wall of a module housing, and includes a spherical lens fastened in the module housing. The metal tubule supporting the optical fiber is adjusted in the flange by axially displacing it a preset focal distance from the spherical lens, and is fastened in the flange. The spherical lens mounting takes the form of a metal tubule and is adjusted at the frontal side of the flange adjacent to the housing by transverse displacement and fastened, so as to achieve optimum alignment of the optical axes of said arrangement, and the flange is hermetically sealed directly or through an annular projection of the spherical lens mounting to the modular housing wall.
