A device for displacing the end of an optical fiber (6) along two orthogonal axes, the device enabling said optical fiber (6) to be aligned with another optical component (4) and comprising a frame (1) on which the optical component (4) is maintained together with a non-hinged deformable solid (10A, 10B) having thin blades (14A, 14B) on which the optical fiber to be aligned is fixed, the device being characterized in that the deformable solid is made as a single part and in that the thin blade-shaped portions thereof (14A, 14B) are disposed along the faces of a box-shape whose right cross-section at rest is square and is perpendicular to the axis of the optical fiber (6), one of the two ends of a diagonal of this box-shape being fixed to the frame (1) and the other being fixed to the optical fiber to be aligned, with the two ends of the other diagonal each constituting a thrust point for displacement means (20) enabling the right cross-section of the box-shape to be deformed.

Device for displacing the end of an optical fiber along two orthogonal

In a fiber-gripping device has a gripper head provided with a V-groove for housing an optical fiber and an elastically deformable holding member which is brought to bear on the optical fiber. The gripper head and holding member are provided with V-section channels located respectively in oppositely-facing relation. A cylindrical rod forming a pivot-pin is placed between said oppositely-facing channels. The device is caused to open by a spring which tends to produce a movement of pivotal displacement of the holding member away from the gripper head. A locking lever is adapted to move into a first position in which the holding member is located at a sufficient distance from the gripper head to permit free passage of the optical fiber and a second position in which the holding member fixes the optical fiber within its V-groove and exerts a force which is controlled by its own elastic deformation.
