Abstract

L'invention concerne un guide de câble pour une fermeture de télécommunications. Le guide de câble comprend : une première ouverture sur un premier côté ; une deuxième ouverture opposée à la première ouverture sur le premier côté ; une troisième ouverture sur un second côté, le second côté étant orthogonal au premier côté ; et au moins un élément arqué faisant saillie à partir d'une base du guide de câble et définissant une pluralité de passages de câble entre les première, deuxième et troisième ouvertures. Un gestionnaire de câbles est prévu pour gérer les câbles entrant et sortant d'une colonne de plaques à rainures. Un canal de guidage de câble gère les câbles entrant dans le gestionnaire de câble. Le canal de guidage de câble peut présenter la forme d'une trompette dont une extrémité est plus grande qu'une extrémité opposée. Le canal de guidage de câble peut comprendre une construction flexible dans laquelle une seconde extrémité distale peut être positionnée dans de multiples positions par rapport à une première extrémité proximale.
