PROTECTIVE ASSEMBLY FOR THE INTERNAL HEATING OF A METAL TUBE CONTAINING AT LEAST ONE OPTICAL FIBER AND METHOD FOR IMPLEMENTING THE SAME

摘要

The protection assembly against the internal heating of a metal tube containing at least one optical fiber limits the heating of the fibers inserted by an auxiliary tube and the filling gel, to the right of the closure by laser welding of the metal tube. BR/ It is characterized in that it comprises a thermal diffuser (15) interposed between the auxiliary tube (10) for insertion of fibers (11) and the closure zone defined on the metal tube (6). Application: Underwater Optical Cable.
