A repair line for repairing a closure defect in a metal tube containing at least one transmission optical fiber which includes a repair station having a tube conditioning system for bending and tensioning a portion of the tube including the defect and a laser for welding point by point along the defect with the minimum heat input at each point.

Laser welding line for repairing a closure fault of a metal tube

A method of repairing a closure defect in a metal tube containing at least one transmission optical fiber entails bending and tensioning a portion of the tube including the defect and laser welding point by point along the defect within the bent portion with the minimun heat input at each point.

Method for repairing a closure fault of a metal tube containing at least

Junction box for joining the ends of two underwater optical fiber cables by welding, comprising two clamps 1, 2 connected by a tubular sleeve 3, and a central hollow mandrel 17 for securing the welds, wherein said mandrel comprises a slack chamber 15, 16 in between each clamp and one end of the mandrel. Such junction boxes are mainly for use in the junction of underwater telecommunication cables.

A device for joining an underwater optical fiber cable and a repeater comprising a fiber feed-in cable, the end of said underwater cable being secured in a jointing block by means of a tapered ferrule and hard-setting resin filler, said device comprising a slack chamber for storing surplus lengths of optical fiber, said slack chamber interior being bounded on the underwater-cable-side by a storage canister having a bulged internal wall the radius of curvature whereof is everywhere greater than or equal to the minimum acceptable radius of curvature for the optical fibers, and on the fiber-feed-cable-side by a plug having a conical internal surface. Device is mainly applicable to the joining of undersea telecommunications cables.
