Abstract: The connector comprises an optical fibre (2) provided with a core (5), a cylindrical termination (3) for containing the connecting end (11) of the fibre and a mechanical connection assembly (4). The core connection end (12) is made to coincide with the axis (10) of the termination and is then fixed with respect to the latter, and the active ends (36, 39) of the termination and of the fibre are then polished. The coincidence is brought under optical control by acting on the means (14) for displacing and fixing the fibre in the termination.

Abstract: A connector for optical fibres comprising means (1, 2) for retaining the extremities (3, 4) of fibres to be connected, means (7) for assembling and aligning the thus-retained fibres, said means being adapted to maintain the plane front surfaces (5, 6) of the fibres to be connected opposite to each other, so that the optical axes of said fibres be aligned, wherein said aligning and assembling means (7) contain a barrel in two parts (8, 9) provided with bores in which are respectively engaged the retaining means of said extremities to be connected, said two parts of said barrel having front surfaces (5, 6) opposite to each other and parallel with those of the fibres, as well as means (12) for aligning said fibres to be connected, removable means (18, 19), an internal portion of which is adapted to maintain said front surfaces (5, 6) of the two parts of said barrel in contact with each other through abutment means (16, 17), and resilient means (20, 21) adapted to maintain tightness about said front surfaces (5,
