Study on dense multi-fiber backplane for a large-scale switching system

Dense multi-fiber backplane has great prospect in large-scale multi-rack connection system and optical Routers next generation as connecting equipment. The operation principle of multi-fiber backplane is presented in this paper. In order to conquer the difficulties in producing and upgrading the backplane with dense multi-fibers, starting from the traditional crossbar structure in switching backplane, an original method for optimizing the configuration of fiber circuit on backplane is adopted, and applied to the preparation of backplanes. An experimental setup and flow of producing are also proposed to predigest the process of producing. The advantage of this proposed method in maintaining and upgrading the backplane is proved through the achievement of two sample backplanes with 8(×8) × 8(×8) and 12(×8) × 8(×12) configuration and their testing results.
