1. A subsea housing assembly, comprising:
a subsea housing;
a first housing portion of the subsea housing, wherein the first housing portion comprises a first electrical connection for data communication;
a second housing portion of the subsea housing, wherein the second housing portion comprises a second electrical connection for data communication;
a wall providing separation between the first housing portion and the second housing portion of the subsea housing; and
an inductive coupler comprising a first coupling section disposed in the first housing portion and a second coupling section disposed in the second housing portion, wherein the inductive coupler is configured to provide inductive coupling across the wall for providing at least a data communication between the first electrical connection in the first housing portion and the second electrical connection in the second housing portion;
wherein the first coupling section comprises an inner coil and the second coupling section comprises an outer coil, or wherein the first coupling section comprises an outer coil and the second coupling section comprises an inner coil;
wherein the outer coil at least partly surrounds the inner coil;
wherein at least part of the wall extends between the inner coil and the outer coil; and
wherein soft magnetic material is arranged at least around the outer coil and/or inside the inner coil such that a magnetic flux is collected and guided from the outer coil to the inner coil and/or from the inner coil to the outer coil.
