Abstract

A positioning terminal for an optical fibre or a bundle of optical fibres in which the position of the fibre or bundle is defined relatively to a right circular cylindrical external surface. The centering of the fiber or bundle of the axis of the external surface is achieved by compressing a deformable internal cylindrical body arranged in a coaxial hole and traversed by the fibre or bundle through an axial bore. In the case of a bundle, a compact hexagonal arrangement of the individual fibres ends is thus obtained, and by giving to the coaxial hole an hexagonal cross section, the orientation of the hexagonal arrangement can be marked on the terminal external surface. Methods for manufacturing such a terminal and for arranging it at the end of a fibre or bundle are also described.
