A （3,3,2） rectangular CC-Banyan network was studied. According to the construction principle of the CC-Banyan network, the topological graph of （3,3,2） rectangular CC-Banyan network was obtained, and then the routing rule of （3,3,2） rectangular CC-Banyan network was presented. Finally, a optical experimental setup of （3,3,2） rectangular CC-Banyan network was designed. Each stage of node switches consisted of a phase spatial light modulator and a polarizing beam-splitter, and the connection of neighboring stage was performed by a fiber. The theoretical analysis and experimental result show that the experimental setup can realize these functions including optical signal sorting and permuting etc. , which also can be used in the fields of optical communication and optical information processing.
