Optical fibers and optical fiber cables
What is an optical fiber?
An optical fiber is made from glass that is as thin as a human hair. This high-performance medium can transmit optical signals over dozens of kilometers. Unaffected by electromagnetic induction noise, optical fibers ensure high communication stability and enable high-speed, long-distance transmission. Notably, Sumitomo Electric has been developing products with the workability of optical fiber cables in mind. EZremove™-plus offers higher levels of safety than before in the process of extracting optical fibers from optical fiber cables, and significantly reduces the time required for the process (by more than 40%).
Here you will find a selection of our featured products. We offer a rich lineup of optical fiber and optical cable please look at the link below.
Since our founding in 1897, Sumitomo Electric has been pursuing technological innovation along with social development, leading the era of high-speed, high-capacity FTTx communication with world-class manufacturing technology, especially in optical fiber, cable, and components.
