Abstract
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.
