Based on terrain characteristics of transmission lines, this paper compares existing cableway types and put forward working cable arrangement that adopts dual bearing cable and single pulling cable.
Single fiber optic modules with dual fiber cable connections provide redundant point-to-point, star, tree and ring topologies, depending on the communication system.
拥有双重光纤电缆连接的单一光纤模块依据通信系统可以提供点对点，星状，树状以及环形布局。
