Fiber optic cables have now been installed throughout the world, including in Japan. As fiber-to-the-home (FTTH) networks have widely spread, people are increasingly benefiting from data communication services through the use of the Internet and mobile devices. Fiber optic networks, connected throughout the world, fundamentally support the transmission of large amounts of data, which have been increasing each year. To construct such networks, it is crucial to use fiber optic connection technology. This technology is classified into permanent connections—comprising fusion and mechanical splicing—and removable connections using connectors. For connecting long-distance and large-capacity trunk lines, fusion splicing is essential, in which optical fibers are fused together using the heat generated by electrical discharge between electrodes.
The Sumitomo Electric Group undertook the development of an optical fiber fusion splicer in the 1970s. Since the launch of the first unit in 1980, the Group has led innovations as one of a handful of pioneering Japanese manufacturers, and has contributed to constructing global fiber optic networks. A reduction in splice loss and productivity and quality improvements in splicing work have remained constant challenges facing fusion splicers. It is no exaggeration to say that the history of the efforts that the Sumitomo Electric Group has directed toward solving these challenges is the history of fusion splicers. The daring endeavors of the Sumitomo Electric Group in facilitating the evolution of fusion splicers sustain fiber optic networks and the advanced information society. And now, the Group is making its way steadily to become a global leader with its profound product development capabilities and extended sales and maintenance frameworks implemented throughout the world.
