Sumitomo Electric Lightwave (SEL) foresaw the migration to an all optical fiber network as early as 1983 when it first opened its doors in Research Triangle Park, NC.

Our sole dedication to the advancement of optical fiber technology and exceptional service to the customer — then and now — has positioned Sumitomo Electric Lightwave as a major industry leader in the innovation, design, development, and manufacturing of optical fiber and connectivity solutions for fiber optic communication, wireless, residential broadband, CATV, FTTx, data center, and enterprise networks.

By providing the industry’s highest quality, most reliable, and advanced optical fiber, fiber optic cable, fusion splicing equipment & accessories, field installable connectors, passive components,FTTx solutions, and FutureFLEX® Air-Blown Fiber® and Air-Blown Cable, SEL is the trusted solutions provider for today’s most prominent optical fiber outside plant and inside plant network deployments. 

And since we’re a wholly owned privately-held company of Sumitomo Electric Industries (SEI), our primary commitment is not to shareholders, but to you — our customer.

As part of SEI, serving the markets of North, South, and Central America, Sumitomo Electric Lightwave draws not only on its own outstanding R&D, resources and expertise, but also on the vast, worldwide Sumitomo consolidation to address the growing demand for new and better technology.
