1. A fiber plug for optical coupling of a light-guiding fiber with a plug receptacle, the fiber plug comprising:
a plug housing for receiving and locking component parts of the fiber plug in a predetermined position relative to one another; wherein the plug housing includes:
a fiber inlet and a fiber bearing configured for spatially fixed reception of the light-guiding fiber;
at least one optical lens located optically downstream of the fiber bearing along a beam path of light emitted from an end face of the light-guiding fiber and configured for collecting light exiting from the end face of the light-guiding fiber and for collimating the collected light;
a coupling surface with an output of the beam path and with a coupling structure for connection to a receptacle structure, which is complementary to the coupling structure; and
at least one adjustable optical element that is arranged in the beam path optically downsteam of the fiber bearing and optically upstream of the coupling surface, wherein the at least one adjustable optical element is configured to reduce an angle of the beam path with respect to an optical axis of the lens and/or to reduce a spatial offset of the beam path with respect to the optical axis of the optical lens,
wherein the coupling structure has a first component of a magnetic coupling that includes two components and a first component of a kinematic coupling.
