Abstract

The invention relates to an inter-board waveguide-optical fiber coupling system, comprising an adapter board, a waveguide backplane interconnected with the adapter board through a vertical waveguide connector on the board, and a sub-board interconnected with the waveguide backplane through a board edge waveguide connector. board; the vertical waveguide connector on the board includes plugs, sockets and vertical steering contacts; the board edge waveguide connectors include plugs, sockets and coupling parts; the vertical waveguide connector plugs on the board and the board edge waveguide connector plugs are respectively equipped with MT Contact Ⅰ and MT contact Ⅱ; MT contact Ⅰ and vertical steering contact can be aligned and mated to realize waveguide-fiber coupling between the adapter plate and waveguide backplane board, and the coupling part and MT contact Ⅱ can be aligned and mated Realize the waveguide-fiber coupling between the waveguide backplane and the sub-board, so as to realize the transmission of optical signals between the adapter board and the sub-board. The invention can realize no fibrillation on the board, rich and flexible interconnection modes between the boards, small installation space and convenient later maintenance.

Description

technical field [0001] The invention belongs to the technical field of optical signal propagation, and in particular relates to an inter-board waveguide-optical fiber coupling system. Background technique [0002] At present, inside the chassis, the optical signal connection between the backplane and the sub-board or the adapter board mostly adopts the optical fiber-fiber mode. One side of the optical fiber ribbon cable is coupled into the chip or optical module on the backplane, and the other side is terminated with an optical fiber connector socket. Correspondingly, the daughter board or the adapter board is equipped with a suitable connector plug. The transmission of optical signals between the backplane and the sub-board or the adapter board is realized by mating the connector plug and the socket. In the above application form, the optical fiber ribbon cable is mostly located on the surface of the backplane. Once the transmission density level is increased, there will b...
