Abstract

Optical or optoelectronic module with an optical bench and a laser diode or group of laser diodes located on its top side and first optical and optoelectronic elements positioned sequentially in the direction of the main beam of at least one of the laser diodes, which include at least a focusing lens as well as an optical fiber with two optical end surfaces where the first optical and optoelectronic elements are located in at a first element holder and with the first element holder jointly form a first optical and optoelectronic module, a first assembly holder is located on the top side of the optical bench. The first optical and optoelectronic elements on the element holder are jointly adjustable in the beam path of the light emitted by at least one laser diode and the element holder is located on the assembly holder in such a way that the first optical and optoelectronic elements located on the first element holder are in the beam path of the light emitted by at least one laser diode, and the focusing lens injects light emitted by at least on laser diode into the first optical end surface of the optical fiber.
