Abstract

L'invention concerne une ferrule qui est destinée à recevoir plusieurs fibres optiques et présente un boîtier DIL (2). Sur la face extérieure dans la région d'au moins une surface latérale (4, 5, 6, 7), le boîtier (2) possède au moins un élément de codage (13, 14). Grâce à cet élément de codage (13, 14), le boîtier DIL (2) peut être enfiché d'une seule façon, par exemple, dans un contenant de ferrule, ce qui permet d'éviter toute erreur de montage.
