The essential requirements for establishing a low-loss and high-speed telecommunication line using optical fibers are high performance and quality splicing technology. The simple connection of optical fibers using optical connectors and mechanical splices is increasing. However, the fusion splice is needed for long-haul and high-capacity trunk communications such as submarine optical fiber cable. This requires not only ultra low loss and low back reflection, but also long-term reliability and strength of the fusion splice. The fusion splice is also used when splicing specialty optical fibers for light amplification and high power laser transmission for use in various medical procedures or machining applications. In addition to the splicing technology, fiber cleaving and splice protection technologies are also important steps in the splicing process. In this paper, we introduce the features of each technology owned by our company.
