Optical access networks will be key infrastructures to realize the multimedia society in the near future. Usually, in the case of trunk line, optical cables are installed under the ground. But optical fiber cables approach to offices and homes for optical access networks, the cables often take forms of aerial cables. Some issues must be considered in the optical cable splicing of aerial routes. This paper discusses some subjects; for example, a spare length of the fiber in a cable closure should be short and the splicer should be light weight and compact size to ensure easy operation in the aerial site. This paper also proposes two types of fusion splicers and a useful operation table for aerial optical cable splicing.
