The present invention is applicable to the field of communications technologies, and provides an orthogonal interconnection system and a communications device. The perpendicular and orthogonal interconnection system includes a first board group, a second board group orthogonal to the first board group, and a center backplane arranged between the first board group and the second board group, where the first board group includes a plurality of first boards parallel to each other, and the second board group includes a plurality of second boards parallel to each other; a plurality of right angle male connectors is arranged on each of the first boards, a plurality of right angle female connectors is arranged on each of the second boards, and the right angle male connectors and the right angle female connectors directly cooperate and are connected in one-to-one correspondence. In the present invention, the right angle male connectors and the right angle female connectors directly cooperate and are connected. When the perpendicular and orthogonal interconnection system is upgraded, only the board that permanently has the right angle male connectors and the right angle female connectors needs to be replaced, which is rather simple and shortens a signal link. Based on the foregoing advantages, the perpendicular and orthogonal interconnection system is applicable to various communications devices; therefore, its upgrade is convenient, signal quality is improved, heat dissipation is ideal, and material costs are saved.
