Sumitomo Electric is a large, diversified Japanese manufacturer of electric wire and cable. Its businesses span automotive wire harnesses, fiber-optic and communications cable and components, electronics, energy and power cable, and industrial materials.
Its infocommunications business supplies optical fiber and components, and NVIDIA lists it in its silicon photonics (co-packaged optics) ecosystem; but optics is one segment of a conglomerate whose largest business is automotive wiring, so AI is not its main economic driver.
Sells wire harnesses to automakers, plus fiber-optic cable, optical components, power cable, electronic parts and industrial materials to industrial and network customers.
