Title (EN) OPTICAL FIBER CABLE ASSEMBLY COMPRISING OPTICAL TRACER FIBER
(FR) ENSEMBLE CÂBLE À FIBRE OPTIQUE COMPRENANT UNE FIBRE DE TRACEUR OPTIQUE
Abstract:
(EN) An optical fiber cable assembly is provided including a tracer light source and an optical tracer fiber physically coupled to or surrounded by the cable jacket and defining a tracer scattering profile comprising a relatively high scattering loss at a tracer wavelength or wavelength range λT such that light is dispersed from the optical tracer fiber along at least a portion of its length. At a bend radius of less than approximately 25 mm, the scattering profile of the optical tracer fiber generates dispersed light of a luminance that is at least about twice light generated in a zero-bend portion. The optical intensity of the tracer light source is sufficient for the luminance of the dispersed light at λT or λT* to be at least approximately 80 cd/m2 at bend radii of 20 mm and below.
(FR) La présente invention concerne un ensemble câble à fibre optique comprenant une source de lumière de traceur et une fibre de traceur optique accouplée physiquement à la gaine de câble ou entourée par celle-ci et définissant un profil de diffusion de traceur présentant une perte de diffusion relativement élevée à une longueur d'onde ou à une plage de longueurs d'onde de traceur λT telle que la lumière soit dispersée à partir de la fibre de traceur optique le long au moins d'une partie de sa longueur. À un rayon de courbure inférieur à environ 25 mm, le profil de dispersion de la fibre de traceur optique génère une lumière dispersée d'une luminance équivalente à au moins environ deux fois la lumière générée dans une partie de courbure nulle. L'intensité optique de la source de lumière de traceur est suffisante pour que la luminance de la lumière dispersée à λT ou λT* soit au moins équivalente à environ 80 cd/m2 à des rayons de courbure inférieurs ou égaux à 20 mm.
