1. A joint assembly for a first and a second power cables each comprising at least one optical fiber cable at a radial position different in the first and second power cables, the joint assembly comprising:
a two-halved inner shell and a two-halved outer shell each extending along a longitudinal axis,
wherein:
the two-halved inner shell is adapted to be arranged around a metallic layer of one of the first or second power cables, and the two-halved outer shell is adapted to be arranged around the two-halved inner shell;
at least one half of the two-halved inner shell comprises a first though hole and a first groove in its radially inner surface, the first groove running in a first direction from the first through hole to a longitudinal end of the at least one half of the two-halved inner shell; and
at least one half of the two-halved outer shell comprises a second through hole and a second groove in its radially outer surface, the second groove running in a second direction from the second through hole to a longitudinal end of the at least one half of the two-halved outer shell,
wherein in an assembled configuration the first through hole and the second through hole are substantially superposed to create a single passage, and the second direction is opposite to the first direction.
