Abstract: The optical fibers are enclosed in a protective metal tube in such manner as to impart surplus length to them, the tube being shaped from an initial strip, then laser welded, and optionally swaged as it advances in line. The method of obtaining the surplus length of a predetermined value consists in subjecting the tube as driven to subsequent stretching of a predetermined value by means of a capstan working at constant torque, thereby causing the fibers to advance in the welded tube, then in relaxing the stretched tube. Application to a line for enclosing optical fibers in a protective tube.

Abstract: An optical fiber cable connection organizer device includes a support assembly with lateral accessways for the fibers of the cables, an arrangement for holding splices between the fibers and an arrangement for stowing a surplus length of the jointed fibers. It further includes two sets of magazines for stowing additional slack in the fibers from the two cables. Applications include submarine optical fiber cable joint boxes.
