Abstract

Un boîtier de connexion de câble optique de type capsule comprend une base (1) et une enveloppe tubulaire agencée sur la base (1). Un passage de câble optique (11) permettant l'entrée et la sortie du câble optique est formé sur la base (1). Un support fixe (4) est monté sur la partie supérieure de la base (1). Un côté du support fixe (4) est relié de manière fixe à un support de panneau fixe (5) et l'autre côté est relié de manière rotative à un support de panneau mobile (6) ménagé en regard du support de panneau fixe (5). Une pluralité d'unités d'épissage par fusion de fibres optiques (7) sont ménagées sur le support de panneau fixe (5) et le support de panneau mobile (6) respectivement. Le boîtier de connexion de câble optique de type capsule offre une capacité élevée et peut être élargi à tout moment. Puisque le support de panneau mobile (6) peut être pivoté par rapport à la base (2), la manipulation s'en trouve simplifiée.
