Abstract
This invention relates to an optoelectronic transceiver which has the following: an optical transmitter, an optical receiver, coupling means consisting of a first and second optical lens made with optically active interfaces for changing/deflecting optical paths of on the one hand optical output signals A of the optical transmitter to a connectable optical light guide and on the other hand of input signals E of the same light guide to the receiver, characterized in that the first lens has a concave reflection surface which lies inside in the coupling means for signals of the optical transmitter and the second lens has a convex transmission surface which lies outside for outgoing signals of the optical transmitter and a concave reflection surface which lies inside for incoming signals.

An optoelectronic component which has the following:
- an optical component which emits optical signals to an input/output end face of a light guide and/or
- receives optical signals and converts them into electronic signals, a component carrier located on the optical component [sic], and
- a housing part which surrounds the optical component and which has coupling means which forms optical coupling means and mechanical coupling means (alignment means), the optical coupling means routing the optical signals coming from the optical component to the input end face of the light guide and/or routing the optical beams emerging from the input/output end face of the light guide to the optical component, the mechanical alignment means aligning the light guide with respect to the optical component for efficient signal transmission.
An optoelectronic component which has the following:

An optical coupling device with both optical and also mechanical coupling means in the form of a component housing which combines the optical fiber alignment (physical or mechanical light guide alignment) and the beam deflection which ensures an almost vertical radiation incidence in the input end face of the light guide, this preferably taking place in the beam deflection by means of collimation.
A coupling device with a housing for efficient coupling between an optical fiber and an optical element (transmitting and/or receiving element), preferably with 90° beam deflection, the coupling providing for an optical fiber alignment and beam deflection as well as focusing, and specifically by providing or molding a molded highly transparent plastic body which forms the optical coupling device directly on a carrier which bears the active element(s), the plastic body forming the optical coupling device, i.e. the first housing part of the housing whose second housing part is formed for example by the carrier.
