An ODI hybrid wet-mate connector provides > 1 Gbs video transmission capabilities and power to the RSN-OOI-NSF high definition camera that was deployed during the VISIONS'13 Expedition. The wetmate connectors allow an ROV to connect and disconnect infrastructure underwater without having to recover the equipment. The camera shown here is at a water depth of ~ 5000 ft at the summit of Axial Seamount.
