A fiber-optic splice having a first fiber-optic cable including a first metal tube, the first metal tube including a first metal material, a splice tube including a second metal material, wherein the splice tube is arranged around the first metal tube, or wherein the first metal tube is arranged around the splice tube, thereby forming a first overlap section between the splice tube and the first metal tube, and a first coating including a third metal material, the third metal material being different from the first metal material and the second metal material, the first coating being arranged at an inner surface of the splice tube or at an outer surface of the splice tube in the first overlap section, and wherein the inner surface of the splice tube or the inner surface of the first metal tube includes a first radial deformation providing contact between the splice tube and the first metal tube via the first coating in the overlap section, so that a hydrogen tight seal is achieved between the first metal tube and the splice tube.

Fiber-optic splice and method for producing a fiber-optic splice

A multi-phase submarine power cable including: a plurality of power cores arranged in a stranded configuration, and a curvature sensor including: an elastic elongated member, and a plurality of Fibre Bragg Grating, FBG, fibres, each FBG fibre extending axially along the elongated member at a radial distance from the centre of the elongated member; wherein the elongated member extends between the stranded power cores along a central axis of the multi-phase submarine power cable.
