An apparatus for rotating a fiber about its longitudinal axis and its use for the connection of optical fibers

The invention relates to an apparatus for rotating the optical fiber for connection. It comprises a device (32) of rotation which can be connected to a guide device (2) and which comprises a body (33) containing a rotary ring gear (37) on which a platform (31) is connected. The fiber (1) is conventionally fixed to the platform (31) and can be rotated by means of a motor (43) to be properly oriented relative to the other fiber to which it must be connected. Application area: connecting polarization-maintaining fibers.
