<p>According to the device of the invention, optical coupling is provided by means of one or several parallel ray beams (Ft) of annular cross-section, transmitted in unidirectional or bidirectional form, between two ferrules (1, 2) mechanically coupled by a joint (3) rotating about an axis of rotation ( DELTA ), with which the beam(s) are coaxial. Mirrors (M1, M2) inclined at an angle of pi /4 radians relative to this axis ( DELTA ) each fold the beam, or beams, back on itself through pi /2 radians towards opto-electronic means of generation and/or detection (f1, L1, 11, 21, L2, f2). The axial region which is left clear may be used to establish a connection by electrical path (C1, C2, 6). <IMAGE></p> |
