These products are made by Lightera™, but are marketed by Furukawa Electric. Imagine a technology leap that doubles a cable's fiber optic density while reducing the size of that. Optical fiber cables are the key component that determines communication performance, and it is desirable to have the smallest diameter, lightest weight, and highest density as possible. (SEOF) Company Profile: SEI Optifrontier Co. (SEOF) is a subsidiary of Sumitomo Electric Industries, one of. SpiderWeb Ribbon® (SWR®) is our innovation-packed, market-leading ribbon fibre technology. The digital future and the digital present require extensive fibre connectivity; SWR is one of many solutions from Fujikura which allow fibre deployments to happen faster and more cost-effectively.
