SEI Optifrontier Co., Ltd. has been inaugurated as the result of the merger between Toyokuni Electric Cable Co., Ltd. and Sumiden High Precision Co., Ltd. The former had mainly manufactured various types of optical cables, optical couplers, and optical splitter modules, and the latter had manufactured optical connectors, optical stubs/receptacles, precision processing parts, and tools for network construction. We have inherited the FTTH products and technologies that the two companies had been nurturing, and will strengthen the partnership with the information-related business units of Sumitomo Electric Industries, Ltd.
