As the optical fiber network continues to spread on a global scale at a rate unsurpassed, Fujikura has played the leading role in the area of various optical-related devices, including optical fiber. In particular, as with the "fusion splicer" essential for connecting optical fibers, the Company maintains the No. 1 market position with its share exceeding 50%. Our efforts toward the development of the "fusion splicer" started at almost the same time as research & development of optical fibers and was truly a decision symbolizing the challenging sprit of Fujikura. While the trials to create from zero an unprecedented device presented an incessant series of hardships, we at last completed a machine that could be called an invention of Fujikura. Here, we would like to trace the challenges in the Company's survival … going back to a time before Fujikura achieved the No. 1 world market share.
