The transfer splicing of optical fiber cables is performed at night using released circuits; this involves time‐consuming manual work. To achieve highly efficient optical cable transfer splicings, development of low‐loss transfer components is expected to speed up transfer operations. This in turn reduces interruption time and identification of cable fibers and also controls synchronization of each function and details required. This paper proposes an efficient system for the optical transfer splicing of the existing cables to the new ones. This system uses single‐mode multifiber connectors. The design method and related details of rapid transfer, fiber identification and synchronous transfer control are described. The transfer splicing characteristics of this newer, more efficient system are evaluated and it is verified experimentally that satisfactory results are possible.

This paper will discuss optical fiber cable distribution networks for accomodating the immediate introduction of optical subscriber networks. The concepts of cable distribution system design, the maintenance systems and the cables and jointing technology for supporting these systems will be discussed. The results of experiments using related technology will also be discussed.
