Abstract : In practical optical cable transmission systems, efficient, stable, and reliable fiber splice techniques are required for optical transmission line construction. This paper describes design and performance of an arc-fusion splice machine, a fiber cutting tool, and a reinforcement for spliced portion. Field trial results on the splice are also discussed. In order to assure long-term stability and reliability, stresses applied to fiber inside the reinforcement element due to fiber buckling, torsion and pushing out from the plastic coatings are clarified. It is also varified that proof testing with the proof stress of approximately 180 g is necessary for long-term endurability of fiber against the applied stresses. (Author)
