Abstract

Arc fusion splicing with high strength is important not only for manufacturing ultralong cables but also for field splicing with high reliability, such as for submarine cables. The main causes of loss of fiber strength during the splicing process are believed to be mechanical removal of the fiber coating layer and direct contact with the fiber chucking mechanism of the splicer. Some results of attempts to maintain high-strength splicing have already been reported. However, these methods and equipment were not easy to use because of a special splicer¹ or fiber etching with fluoride acid.²
