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%).
