The present invention concerns a multi-fiber optical connection endpiece, an optical fiber connector using such an endpiece, as well as an apparatus for mounting fibers in the said endpiece. This connector comprises a reference plane of the connection and two cylindrical measuring rods substantially perpendicular to this plane. Each endpiece comprises an endpiece reference plane of the endpiece bearing on the connection reference plane and two V-shaped channel grooves on its rear face from where issue fibers situated at a precise coordinate with respect to the endpiece reference plane. The endpieces are aligned when the V-shaped grooves abut on either side of the measuring rods.

The invention relates to the field of connectors for optical monofibres. In the case where the monofibre (1) is covered by a flexible sheath or envelope (3), the fixing in a connector end fitting may suffer from poor concentricity. According to the invention, a deformable cylinder (4) is placed round the fibre and to said cylinder are applied forces (P) balanced in four perpendicular directions transmitted to the flexible sheath (3) of the fibre by four, internal clamping jaws (31), which bring about a spontaneous recentering of the fibre by the creep or flow thereof. The cylinder is then placed in the end fitting. The applications relate more particularly to optical fibres with plastic sheaths for telecommunications purposes.

Connector end fitting for optical monofibre

In order to make a connection between the fibers of an optical transmission line, the end portion of each fiber is centered in a connector terminal by means of a reference dihedron. The terminal is applied against the faces of the dihedron at one end. The other end of the dihedron is fitted with a set of two packing-blocks and two cylinders for positioning the optical fiber in the bisecting plane in a direction parallel to the edge of the dihedron. The fiber is finally fixed in position by means of a suitable adhesive.
