Abstract

An optical backplane connector (6) with a board (1), detachable in a direction perpendicular to the surface of the backplane, that is, capable of insertion and removal, and arranged on a backplane (12) with an optical transmission path (17) )superior. The optical backplane connector (6) accommodates the photoelectric conversion module (14) in such a way that the incident and outgoing light is perpendicular to the backplane (12), and the transparent plate (15) on which the photoelectric conversion element (7) is installed is perpendicular to the plate (1) and parallel to the back plate (12). Conduction between the electrical contact (13) of the photoelectric conversion module (14) and the internal electrical contact (5) of the optical backplane connector (6) is maintained by mechanical contact. At the end of the optical transmission path (17) on the backplane (12), an optical connector (10) with a 45° mirror (16) and guide pins (9) is installed. The positioning operation is realized by fitting the guide pin (9) of the optical connector (10) into the guide hole (8) of the photoelectric conversion module (14).

Description

technical field [0001] The invention relates to an optical backplane connector, a photoelectric conversion module, an optical backplane, an optical transmission device and a photoelectric conversion method, which are used for optically interconnecting circuit boards in information equipment such as routers or servers. Background technique [0002] In recent years, the amount of information flowing through networks has increased through the expansion of broadband networks, and the information processing capacity in information devices such as routers or servers has required improvement. However, the transmission rate limitation of circuit boards used in equipment constitutes an obstacle to improvement of equipment capacity. In order to break through this barrier and further increase the information processing capacity in an information device, optical interconnection of a plurality of boards accommodated in the device is effective. In order to complete the optical interconne...
