Abstract
A rotary transmitter for transmitting optical signals between two components is described. In accordance with the invention, provision is made for a fiber optic cable, optionally also a second fiber optic cable to be used to transmit the signals, the latter being suited, due to their surface treatment, to coupling signals of send elements and forwarding them to an interface in order to be registered there by a receive element. The fiber optic cables are laid such that they describe a circle upon which the transmission elements rotate about an axis of rotation. As a result, a complete data transmission is possible by way of the waveguide. The components (send elements, receive elements and the optical fiber cables) can be fastened to an annular printed circuit board by SMT.
