Optical interconnection assembly and optical interconnection device

The invention relates to an optical interconnection assembly and an optical interconnection device, a limiting cylinder is connected with a coupler through a connector, the bottom surface of the limiting cylinder is provided with at least two power connection columns, and the at least two power connection columns are used for being correspondingly connected with optical fibers of a plug; a sliding groove is formed in the inner side wall of the limiting cylinder. The protection plate is located in the limiting cylinder and surrounds the at least two power connection columns in the circumferential direction, a sliding block is arranged on the side wall of the protection plate, and at least part of the sliding block is embedded into the sliding groove; the reset structure is arranged on the protection plate in the limiting cylinder; when the protection plate is extruded by the plug, the sliding blocks are driven to slide in the sliding grooves, and the power connection ends of the at least two power connection c
