PROCEDE DE PROTECTION D'UN ENSEMBLE DE FIBRES OPTIQUES SOUDEES ET DISPOSITIF ASSOCIE

摘要

The invention concerns a method for protecting an assembly of N weld zones of N pairs of optical fibres. The invention is characterised in that the protection method comprises the following steps: placing the ends of N homologous optical fibres (fa) inside a lining tube (42) made of thermofusible material, arranging a reinforcing element (43) along the optical fibres proximate to said weld zones (1) and placing the lining tube and the reinforcing element inside an outer envelope (41) made of thermoshrinkable material; welding the N pairs of optical fibres; bringing the lining tube (42) and the outer envelope (41) around the N weld zones (1); heating until the thermoshrinkable material of the outer envelope (41) is shrunk and melting the thermofusible material of the lining tube (42). The invention is useful for connecting high-capacity optical fibre cables.
