Abstract: To meet the requirements of high signal rate, large exchange capacity as well as high port rate and backplane interface exchange rate in the railway communication platform, this paper presents the design of an interconnection system scheme for the photoelectric hybrid backplane. It also introduces the overall implementation scheme of this interconnection method, the implementation scheme of various modules, and the communication process of high-speed signals and low-speed signals. The proposed interconnection scheme can solve the problems of the existing interconnection technology for the optical backplane, including fixed optical connection topology that cannot be changed at any time, separate application of electrical connector and optical connector, large space occupation and high cost.

Key words: communication platform, photoelectric hybrid backplane, interconnection system, fiber bundle, plugboard, optical-electricity conversion module
