The invention relates to an optical transceiver unit (200) comprising a carrier (210) that can be rotated about an axis of rotation (206), an optical receiver (204) which is arranged on the carrier (210) on the axis of rotation (206) in order to receive an optical receiving signal (226) from a first direction, an optical transmitter (202) which is arranged on the carrier (210) that is adjacent to the optical receiver (204), in order to transmit an optical transmission signal in a second direction, and an optical transceiver system (214) which is arranged on the carrier (210) on the axis of rotation (206) above the optical receiver (204) and extends over the optical receiver (204) and the optical transmitter (202). The optical transceiver system (214) comprises an optical receiving system (218) and an optical transmission system arranged in the optical receiving system (218). The optical receiving system (218) is designed to guide the optical receiving signal incident on the transceiver unit (214) towards the optical receiver (204) on the axis of rotation (206), and the optical transmission system is designed to move the optical transmission signal (208) on the axis of rotation (206) emitted by the optical transmitter (202) such that a transmission signal (226) exits the transceiver system (214) in the region of the axis of rotation (206).
