An inventive rotatable optical short-range transceiver has: a support which is rotatable around a rotation axis, an optical receiver which is arranged at the support on the rotation axis to receive an optical reception signal from a first direction, an optical transmitter which is arranged at the support to be adjacent to the optical receiver to emit an optical transmission signal in a second direction, and an optical transmission/reception unit which is configured to allow interruption-free rotatable optical data communication, wherein the optical transmission/reception unit is arranged at the support above the optical receiver and extends over the optical receiver and the optical transmitter, and wherein the optical transmission/reception unit has a support structure for mounting at the support, which is implemented integrally with the optical transmission/reception unit.
