Abstract

To construct low-loss economical optical transmission lines using single-mode fiber cables, it is necessary to develop a splicing technique which can be used to join single-mode fibers with some core eccentricity and outer diameter discrepancy. Even for these fibers, low-loss arc-fusion splicing is expected with a precise core axis alignment technique in optimum fusion conditions. In this paper, we describe the optimum fusion conditions for low-loss splicing, construction of a splicing machine that realizes high-speed automatic axis alignment, and field trial results using the machine.
