Abstract
A system for connection by means of optical fibers for the bidirectional exchange of data between a fixed central unit and peripheral units integral with a frame driven with a rotary movement, this system comprising radiating energy emitting and receiving means situated in the fixed part, coupled by optical fibers forming unidirectional data exchange paths to a single mixing fiber, itself coupled to optical fibers forming bidirectional data exchange paths coupled to radiating energy emitting and detecting means associated with the peripheral units integral with the mobile frame. Furthermore, the mixing fiber is split into two parts coupled together by a rotary optical joint.
