Abstract
The invention relates to a coupling unit for coupling an optical transmitting and/or receiving module to an optical fiber. The coupling unit has a connecting area that can be connected to a transmitting and/or receiving module, and a holding area that holds an optical fiber. A transparent coupling area is provided, which is formed as an integral component of the coupling unit, and via which light can be coupled directly between an optical fiber that is inserted into the holding area and a transmitting and/or receiving module that is coupled directly to it. The coupling area preferably has a matched refractive index. The coupling unit is preferably in the form of an injection-molded part.
