A fiber optic terminus (10) for use in fiber optic cable connections which terminus (10) includes an optical fiber (12) disposed within and supported by a ferrule (24). The end surface (52) of the optical fiber (12) is recessed or undercut relative to face surface (28) of the ferrule (24). In another embodiment of the invention, the face surface (28) of the ferrule (24) defines a surface angle which is less than about 2.0 degrees. The fiber optic terminus (10) is fabricated by stripping a fiber optic cable (8) bonding the stripped-end of the fiber optic cable (8) to the ferrule (24), cleaving the optical fiber (12) in closed proximity to the face surface (28) of the ferrule (28), polishing the cleaved-end of the optical fiber (12) to achieve the terminus end profile (50) and inspecting the polished-end of the optical fiber (12).

L'invention concerne un bornier (10) de fibre optique à utiliser dans les connexions de câbles à fibre optique, bornier (10) comportant une fibre optique (12) placée dans une ferrule (24) et supportée par celle-ci. La surface d'extrémité (52) de la fibre optique (12) est en retrait ou entaillée par rapport à la surface frontale (28) de la ferrule (24). Dans un autre mode de réalisation de l'invention, la surface frontale (28) de la ferrule (24) définit un angle de surface ? qui est inférieur à environ 2 degrés. On fabrique ledit bornier (10) de fibre optique en dénudant un câble à fibre optique (8) de sorte que la fibre optique (12) soit exposée, en liant l'extrémité dénudée du câble à fibre optique (8) à la ferrule (24), en fracturant la fibre optique (12) très près de la surface frontale (28) de la ferrule (28), en polissant l'extrémité fracturée de la fibre optique (12) de sorte que le profil d'extrémité (50) du bornier soit obtenu et en inspectant l'extrémité polie de la fibre optique (12).
