Development of "Ultra Low Attenuation Optical Fiber", the Symbol of Fujikuraism Now, the world is in the midst of building a notable change in history with the IT revolution. We can no longer stop the flow of such history, one that has greatly changed people's daily lives, not to mention the industry. What ignited this IT revolution was the development of optical fiber. Fujikura contributed a great deal to the technological evolution of optical fiber cables that enable large volume transmissions of data. Its progress was filled with incessant challenges and creation. And finally, Fujikura achieved a global accomplishment that later motivated the IT revolution. Here, we trace the development of an optical fiber developed by Fujikura that has been so highly praised as being described as a "A gift from God."
